​After discussing with ffesti in #rpm.org about it, I've added a patch to
the pull request that introduces the "--legacy"​ switch, which will produce
pythonegg(X)(M) Provides so that Mageia has a transition path. Just set up
your pythondistdeps.attr with it, and you'll have pythonegg(X)(M) format in
Provides, though Requires will automatically change to the newer format (it
won't break things built with your generator, though, since you'll have the
legacy Provides enabled). An example file is shown below:

%__pythondistdeps_provides	%{_rpmconfigdir}/pythondistdeps.py
--provides --legacy
%__pythondistdeps_requires	%{_rpmconfigdir}/pythondistdeps.py --requires
%__pythondistdeps_path	^((/usr/lib(64)?/python[[:digit:]]\\.[[:digit:]]/.*\\.(py[oc]?|egg.*|dist-info))|(%{_bindir}/python[[:digit:]]\\.[[:digit:]]))$
%__pythondistdeps_magic	[Pp]ython.*(executable|byte-compiled)

​
This version is also Python 3 compatible, so you can prefix the calls with
/usr/bin/python3, if you wish.​
