Search for "python2" instead of "python" and you will find them. Just
yesterday I had an email exchange about this with a redhat guy. He
said that Redhat doesn't want to break binary compatibility from
python 1.5.x in a series (7.x) so they are packaging python >= 2.0
under the "python2" name and including both.
So I would say the "right" way to install rdiff-backup is probably
1. Install the python2 package, leaving python 1.5 the way it is
2. Install the rdiff-backup RPM, using --nodeps if it only complains
about python missing.
3. Edit the first line of rdiff-backup so it says
so "python2.2" gets run instead of "python" (which is 1.5)
Another way (I actually run Redhat, and this is what I did) is just to
grab any python2.2 SOURCE rpm and --rebuild it. Source rpms work
great and are probably the answer to 90% of the dependency problems
people complain about with rpms.
In the future I should probably build special rh7x rpms that do
steps 2 and 3 above automatically.
