The Fedora Core 1 RPMS can be used on RH9 as well.

Now you got python2.3.3 (from source).

Nearly any RPM out there requires other RPMS to be installed. _No_ RPM 
will ever recognize custom from source whatever installations. You are 
_not_ doing a from source installation. You are trying to rebuild a 
source RPM which is quite different. Rebuilding source RPMs requires 
other RPMs and its devel packages. You build a RPM from the source RPM 
which is afterwards installed. During this process the RPM system 
verifies that all dependencies are resolved. (Custom) from source 
installations of whatever dependency are not supported inside this 
process of course.

Its not that we insist on this thing .. but there is no other way 
besides including python inside the plone rpm as well which i am not 
willing todo. The requirements are clearly stated on my rpm project page 
at http://longsleep.org/projects/plone2-rpms, which was linked from the 
download page once, but isnt anymore. Without this information i agree 
its kind of difficult to resolve the plone rpm dependencies.
