Dear VMD experts,

I was going to use vmd-1.9.3 with python, in linux. But it couldn't import
any python module and showing the following error --
vmd > gopython
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
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ValueError: vmdnumpy module not available.
Info) Text interpreter now Python
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/vmd/scripts/python/", line 59, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter
Please help me to fix this problem.
