requirements based on application version

[Adam Stokes]

In my case python 2.4 requires an external package 'python-sqlite2'
for the 2.0 api for sqlite3, whereas python 2.5+ provide this without
the need for that extra requirement.

My question is what is normally done about this when someone has to
provide a package for both fedora(python 2.5+) and epel(python 2.4)?
Is it proper to define this within the spec file?

Thanks
