You probably want to rebuild rpm-python against 2.2 on your machine - you
should be able to do this by grabbing src.rpm for your rpm version.  This will
ensure that it is happily linked against rpmlib.  Extract rpm sources using
rpmbuild -bp or rpm2cpio 

./configure --with-python=2.2 --prefix=/usr
make
cd python
mkdir tmp 
make DESTDIR=$(pwd)/tmp install
cd tmp/usr/lib/python2.2/site-packages

To test

python2
import rpm

pop rpmmodule.so somewhere more useful :)

Should leave you with rpmmodule.so you can use.[0]

It's not quite that simple atm.  I need to look at the legacy and future
issues...

rpm-python is currently part of rpm - getting srpms from distro/rawhide or CVS
is authoritative.  Also can be found various releases at ftp.rpm.org - but for
your case grabbing rpm --qf '%{SOURCERPM}\n' rpm, is what you want.
