python-elementtree contains a compiled library (so) which is built
against a specific python ABI. Granted - it might work with a more
recent version, but as the RPM requirements are "only 2.x" unlike the
normal "2.x or higher", I'd tend to think that they know what they're
talking about it. I'm loath to fiddle with it, as yum depends on many
packages to work, python-elementtree being one of the more important and
non-optional ones (see: "redhat sucks").

No, see above. you might want to do something like
rpm -ql python-elementtree | grep so
if you don't believe me. I fully appreciate the fact that they are using
compiled binaries for XML parsing - I use the python native XML parsing
and its slow as molasses.

I think we are confusing different different distributions - fedora has
a single package for both items.

The main problem with most of the above suggestions, is you appear to be
recommending that I forgo the use of automatic installation and
dependency tracking and start to administer my system manually in the
spirit of the old "configure;make;make install" days. Problem is - due
to external time constraints I'm trying to phase away from "managing my
computer" and into "using my computer" ;-)
Seriously - I believe that the purpose of automatic software management
system is to make your work easier, not make it harder and/or force you
to disable parts of it.
Currently I've given up and installed Fedora Core 5 on the development
system, basically postponing the frustrating redhat-induced
software-management-deficiency-syndrome stage to a later stage, although
not alleviating it.
