I don't know how python is implemented, but this looks like a native
object. When I write shared libraries in C, I have similar error
messages on Sparc when I forget to compile them with "-fPIC".
From gcc(1) manual page:

 -fPIC
 If supported for the target machine, emit position-independent
 code, suitable for dynamic linking and avoiding any limit on the
 size of the global offset table.  This option makes a difference on
 the m68k, m88k, and the SPARC. 

The latter sentence explains with so many people apparently don't know
about it (at least I didn't), or why people tend to forget it.

So what I would do first is check whether this library is effectively
compiled with this flag.

HTH,
