[PyMOL] problems updating Mandrake packages

[Austin]

Hello,
I'm the maintainer for the pymol package in Mandrake Linux.
I recently updated it to 0.90, but it won't run now.  I'm not a python expert, 
so maybe someone here could help me interpret the following error?

[aus...@gamma373-165 SOURCES]$ pymol.com
Traceback (most recent call last):
  File "/usr/lib/python2.3/site-packages/pymol/__init__.py", line 92, in ?
    import pymol
  File "/usr/lib/python2.3/site-packages/pymol/__init__.py", line 300, in ?
    import _cmd
ImportError: /usr/lib/libpng.so.3: undefined symbol: deflate

We're currently using python 2.3, pil 1.1.4, libpng 1.2.5.

Any suggestions would be appreciated, as I'm supposed to have this working by 
Wednesday.  I'm not on the list, so a cc would also be appreciated.

Thanks,
Austin
