[GRASS-dev] G65/7 ctypes compilation problem on Enterprise Linux

[Helena Mitasova]

Markus,

this is the same problem here - the problem is with python2.4 that is used as default
and that does not include ctypes so you need to make symlink in grass to make sure 
it looks for python2.6 (which I have also installed) or there may be some other solution -
You cannot remove python2.4 because it is used for system management.
I did not have time to get it fully resolved yet.

The problem should go away with the next release of RHEL which is in beta and
should use python 2.6 (I think),
