Hello,
I have been running into issues with the tcl/tk and python bundles currently distributed with ccp4-6.0.2 (x86 system running Centos5).

1. The tcl/tk/blt package for Linux now extracts into a ./tcltkblt subdirectory. Apart from making upgrades slightly easier, this does not seem to make very much sense to me. The ccp4.setup file created by the install script still points to the standard location (/usr/local/bin) for the binaries, so I suspect the extract path was not intentionally changed.

2. On Centos5 (which comes with python 2.4.3), the python 2.4.2 package provided with ccp4 leads to a dilemma: As soon as /usr/local/bin/python is present, it is also used by standard desktop applications, which leads to undesired effects. For instance, gedit (the standard gnome text editor) complains about missing modules. If /usr/local/bin/python is made unavailable (by renaming, for example), sourcing ccp4.setup leads to an "incomplete libtbx environment" error.

a) Is there a possibility to define the python binary used by ccp4 (similar to the tcltk path in ccp4.setup)? This way you could extract the python package in a different (non-standard) location and avoid interference with other applications.
b) Is the ccp4 python package customized in any way, or is it perfectly ok to use the version which comes with the OS?

Any suggestions?
Oliver
