Sorry about the wild goose chase on the character set thing.  Its
something changeable through an environment variable so its something
that could easily be changed.  At least that would explain the sudden
change in behavior.  After I pursued this line for a little while it
dawned on me that the version of python being reported doesn't make sense.

It looks like the copy of python that's in yum's path has regressed to
something REALLY old.  rpm -q showed python-2.4.3-8.FC4 but yum is
complaining about a problem with 2.4.1 compiled with gcc 3.2.2.  When I
run python from the command line on my FC4 box, I get:

[root bend ~]# python
Python 2.4.3 (#1, Jun 13 2006, 16:41:18)
[GCC 4.0.2 20051125 (Red Hat 4.0.2-8)] on linux2

The version number that python reports matches the version number for
the python rpm.  Also, the gcc version python was compiled with matches
the current version of gcc for FC4.

Try running python (if it will run) from the command line and see what
it gives for a start-up message (ctrl-D to exit the python CLI).  If it
matches the error message you're getting then at least things are
consistent and you may need to just re-install python.  Not sure how
your system got into this state.  If you get the same thing I got
(matches what rpm says is the installed version) then something really
strange is going on.  yum is somehow picking up an old copy of python.

Cheers,
Dave

Ok I've still got a problem I dont quite understand!

So i did this:

rpm -i --force ~alastair/python-2.4.3-8.FC4.i386.rpm

However, python still does this:

[alastair d6173 sh]$ python Python 2.4.1 (#2, May  3 2005, 17:14:18)
[GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.


So which python is first in your PATH?

$ which python

So the only thing that looks like it has been changed is the symlink
/usr/bin/python2

Is there another rpm command I should be using for this?

Was the commercial app that you believe to be the culprit installed using RPM?

Paul.
