 What version of python is this? Running 3.2.23 on python less than
2.6 is, shall we say, less well tested. There's a thread in CentOS about
someone getting packages which work for CentOS-4 (which is python
2.3), and RHEL-5.4 is about to release a 3.2.22 based yum which runs
python-2.4.
 Also, yum/y-m-p on s309x is ... less well tested.

 This looks like a version mismatch for python, or maybe SuSE has the
paths different?

 This pretty much screams "need a newer version of pysqlite".

 They might have a python-sqlite2 packages, which is what RHEL/CentOS
do.
