[PyMOL] PyMol module _cmd version

[Ricardo A. <apa...@if...>]

I am using PyMol version 0.68 and it is very very slow the control of
graphical interface.
I've got the following error when starting the program and I would like
to know if this slow response is a consequence of it:

WARNING: Python C API version mismatch for module _cmd:
  This Python has API version 1009, module _cmd has version 1007.


Where can I get the correct "module_cmd" ?? I am using Linux Mandrake
8.0 on a PIII500 MHz.

Does this problem could be solved installing new PyMol version?

Thank you again,
