It certainly can't be a Python problem; it's got to be RPM or your
source, and I'll hope it's your source.

First of all, I'll assume you're using FC5, especially given your Python
package rev number.

Second, On my FC5 development machine, there are a number of packages
that require python(abi) = 2.4, but I don't see any that use a "=>"
operator the way you do.  If it's good enough for them, perhaps it might
be for you too.

Third, if you're willing to settle for python(abi) = 2.4, then you might
want to look at the source for one of those packages and copy the
Requires line out of the .spec file directly via cut-and-paste, and see
if that solves your problem.

Fourth, if you want to get a list of the names of such packages, here's
how to do it in Bash.  (You could certainly figure it out yourself in a
minute or two, but since I already wrote it, it's faster to
cut-and-paste sometimes):

   rpm -q -a > rpm-q-a
   for r in $(< rpm-q-a ); do
      rpm -q --requires $r | fgrep "python(abi)" && echo "^^^^ PKG: $r"
   done
