What Python libraries are in:

  /usr/lib64/python2.4/config

and:

  /usr/lib64

Ie., the 64 bit lib directories.

It is going to look in the 'config' directory location above first and
if there is only a static library there are not a shared library, it
will probably use the static library. This is because the link line
for library building according to your logs is:

  -L/usr/lib64/python2.4/config
