Well, there is a python RPM in the 'Open Source Software Collection for 
Tru64 UNIX' provided by HP. But it's python version 2.0, so I don't know if 
it's of any relevance to the discussion. This aside, it doesn't have the 
dependency on libz.

I will rebuild and reinstall my local python installation using a dynamic 
libz when the current regression run is finished.

This discussion makes me wonder why other systems are not affected by the 
same problem. There is nothing Tru64 specific at the root cause of this.
