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.
