Hello,

I'm using Mac OS X 10.4.1 and I seem to be running across the same
trouble as some others have experienced with VMD 1.8.3. I've tried
running with the Python libraries that came default with the OS as
well as those I installed using fink. Finally, I downloaded the
binary libraries that are provided (I'm using a case-insensitive HFS+
file system so I had to work around there being a 'Python' directory
and a 'python' binary in the same directory) for OS X but met up with
the same problem. I tried setting the $PYTHONHOME and $PYTHONPATH
environment variables both in ~/.vmdrc and at the text input to no
avail. For example, when I do:

vmd > set env(PYTHONPATH) /tmp/py/lib_MACOSX-numpy
vmd > set env(PYTHONHOME) /tmp/py/lib_MACOSX-numpy
vmd > gopython

I get:

Info) Starting Python...
Numeric Python module _numpy not found; vmdnumpy module not available.
ImportError: Failure linking new module
Info) Text interpreter now Python
Traceback (most recent call last):
  File "<string>", line 1, in ?
  File "/tmp/py/lib_MACOSX-numpy/lib/python2.2/lib-tk/Tkinter.py", line 35, in ?
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter

Other than this issue with Python, the application seems to work fine.
Forgive me if this has been solved already but I only found two
relevant threads in the archives each dating about five months ago.

Regards,
