Hello,

version 6.2.0 of ccp4 has strange permissions set to several setup/configuration scripts which are read while sourcing ccp4.setup.

For a long time, ccp4 packages have been distributed with some arbitrary file and directory ownerships which users are obviously supposed to edit to meet their needs. On unix/linux workstations, we usually install under /usr/local and change all ownerships to root.root (default practice for third-party software).
Up to now, this has not caused any problems.
In version 6.2.0, however, ccp4.setup has permissions rwx r-- --- which makes it unreadable (and un-sourcable) for ordinary users! Strangely, ccp4-others.setup has the usual permissions rwx r-x r-x (although rw- r-- r-- should be sufficient for sourcing).
After rectifying the permissions of ccp4.setup, additional errors appear, concerning permissions of several scripts in the xia2 and phaser trees:
ccp4-6.2.0/share/xia2/setup.csh
ccp4-6.2.0/share/xia2/xia2core/setup.csh
ccp4-6.2.0/share/xia2/xia2/setup.csh
ccp4-6.2.0/src/phaser/bin/machine_type
ccp4-6.2.0/src/phaser/conf/version.csh
All these files have the same problematic permissions as ccp4.setup. After fixing them, ccp4.setup can be sourced without errors.
The bad thing is that there may be many more issues of this kind, which will only surface when trying to run a specific ccp4 program...

Maybe the developers or packagers could comment on this issue. It looks like this ccp4 version is supposed to be installed in a user's home directory, so that he/she can take ownership of all the files.
While in general there is nothing wrong with this type of installation, it should _NOT_ be considered the default on unix-type (i.e. multi-user) operating systems.

Best regards,
Oliver
