Daniel,
Any time you see the "import site failed" error from Python, you can infer that
there is a problem with the Python interpreter being unable to access its
required libraries. Messages after that aren't typically informative.
This usually a path configuration issue, but I think it can also happen when
there is a version mismatch betweehn the executable the libraries (running
python 2.5 executables against 2.4 libraries or vice versa).
If using the system-provided Python, you shouldn't have to set PYTHON_HOME
since it will have been compiled in by default. Try the following in a new
shell:
export PYMOL_PATH=/var/lib/python-support/python2.5/pymol/
python2.5 ${PYMOL_PATH}/__init__.py
Cheers,
Warren

Subject: [PyMOL] python/pymol malfunction on new Ubuntu installation
Dear all
First let me confess that my problem does not just involved pymol.
However, it is hampering my use of pymol amongst other things and there must be
many python experts who read this list.
My problem, on a completely fresh Ubuntu 8.04 install, is that python can find
modules when asked to import them. So
export PYMOL_PATH=/var/lib/python-support/python2.5/pymol/
export PYTHONHOME=/usr/lib/python2.5
python2.5 ${PYMOL_PATH}/__init__.py
gives me
'import site' failed; use -v for traceback Traceback (most recent call last):
File "/var/lib/python-support/python2.5/pymol//__init__.py", line 109, in
<module>
import threading
ImportError: No module named threading
/usr/lib/python2.5 contains site.py, threading.py and all the rest.
Can anyone help? I'd be very grateful.
Daniel
