Hi all,
    I have VMD 1.8.2 and Python 2.3 installed on a Mandrake linux 9.2
machine. I know that this version of VMD runs on python 2.2 but I use
python for other things and don't want to go back one version.
    In fact, VMD can start python, but as one should expect, there are
some problems loading modules:

Info) Starting Python...
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
Numeric Python module _numpy not found; vmdnumpy module not available.
ImportError: No module named _numpy
Info) Text interpreter now Python
Traceback (most recent call last):
  File "<string>", line 1, in ?
ImportError: No module named Tkinter
>>>

Changing $PYTHONHOME does not work probably because it looks for python
2.2 and not 2.3 but I was wondering if there is any trick to make it
work. Could I recompile vmd? Or could I add some symbolic link in
/usr/lib/python2.2 to /usr/lib/python2.3? Or something else? I guess
many users working on new linux distributions are finding this problem...

Thanks in advance,

Ramon
