That is what I was going to ask you? Please try and find out, as
likely what the problem is that that package is requiring a shared
library version/variant which conflicts with version/variant required
by Python. Alternatively it is using a generic name for symbol that
conflicts with something used by another library required by Python or
an extension module.

Please keep followups on the mod_python list by using reply-all.
