Downloaded CCP4 6.0.99 core and phaser. Did gunzip and tar to extract.

Next, the instructions say "for the first 3 tarballs unpack into the
same directory, then configure...make...make install."

I did ./configure and got this:
"
! Please set environment variable BINSORT_SCR (see installation
instructions).
! Please set environment variable CCP4_SCR (see installation
instructions).
! Please set environment variable CINCL (see installation instructions).
! Please set environment variable CLIBD (see installation instructions).
! Please set environment variable CCP4_OPEN (see installation
instructions).
! Please set environment variable PUBLIC_FONT84 (see installation
instructions).
"

So apparently a config file is necessary first. Oops. Full text
of ./configure output is attached.

Please read the following


  NOTICE TO THE LICENSEE

  Please read the following Conditions of Use and the
  appropriate Licence Agreement carefully before completing
  the installation process and using the software. These
  Conditions and the Licence Agreement are legal documents,
  and together contain information on allowed usage of the
  software suite, warranty information and liability disclaimers.
  If you do not agree with these Conditions, then do not
  complete the installation and do not use the software.

  These conditions have been updated for release 6.0 of
  the CCP4 software suite, and all sites are required to
  agree to these conditions of use. You should only be
  prompted for this agreement once.

  The Conditions are as follows:

  a. For commercial users and those doing commercial work:
     Please contact CCP4 at [log in to unmask] to arrange a
     commercial licence. If you have arranged or renewed
     a commercial licence in the last 12 months, then no
     action is required. By agreeing to these conditions, you
     confirm that you have a valid and current CCP4 commercial
     licence.

  b. For users at non-profit sites and not engaged in commercial
     work:
     Please print and complete an Academic licence, sign it and
     post or fax it to CCP4 at the address given on the licence
     (email is not acceptable). A new licence agreement is required
     for CCP4 version 6.0. This licence is valid for 6.0 and subsequent
     versions until further notice. Copies of the licence can be
     found in a  variety of formats in the top directory of the CCP4
     distribution (files "academic_software_licence.*") and on the CCP4
     web site at www.ccp4.ac.uk/ccp4license.html . By agreeing to these
     conditions, you confirm that you have returned a licence
     for CCP4 version 6.0 . It is sufficient to send the licence -
     there will be no confirmation that it has been received.

  I agree to the above conditions and have done the actions
  required.

 Thank you. The CCP4 configure will now run as normal.
srcdir bindir libdir /usr/local/ccp4_master/ccp4-6.0.99e /usr/local/ccp4_master/ccp4-6.0.99e/bin /usr/local/ccp4_master/ccp4-6.0.99e/lib
OK, setting up for a system type of `linux'...


! Using gnu fortran compiler.  If you have an old fortran compiler, you may be better
! off using f2c, see --with-f2c option.

 Will attempt to install the xwindows programs from `x-windows'.
 This is not supported for all systems.
         ******** please note ************
 the xwindows programs will be compiled with an option
 that means errors are ignored. This could result in some
 xwindows programs not being compiled.
 If you want to disable the xwindows programs use --disable-x

 The CCIF library will be built and installed.
 This has been tested on the most common systems, but if
 you have problems, use the --disable-ccif flag.

 The CCTBX library will be built and installed.
 If you have problems, use the --disable-cctbx flag.

 Phaser will be built and installed.
 If you have problems, use the --disable-phaser flag.

 The LAPACK linear algebra package will be included in the installation.
 Configure will search for existing LAPACK and BLAS libraries on
 on your system - if a version of LAPACK is not found then the NetLib
 version will be built for you automatically.
 If you want NetLib LAPACK and BLAS to be used regardless of
 system libraries then rerun configure using --with-netlib-lapack

 To disable inclusion of LAPACK, use the --disable-lapack flag
 (This is not recommended as some programs will fail to build)

 Configure will try to set up and build the CCP4i MapSlicer command
 library, which is required to use the MapSlicer viewer.
 ***** This may not be possible for some systems! *****
 To disable inclusion of the MapSlicer command library, use the
 --disable-mapslicer flag
