Normally I would tell you that you need to address this problem *not*
with us, *nor* with the galeon developers (who have nothing to do with
RPM or yum dependency problems), but on the fedora-list
(http://www.redhat.com/mailman/listinfo/fedora-list/), IRC #fedora or
FedoraForum.org.  But we *did* ask for examples, so here's some free
help with our compliments.  ;-)

I just ran "yum install" and the problem seems obvious to me (and
probably more experienced users), not so much if you're just getting
wet:

[...]
Resolving Dependencies
--> Populating transaction set with selected packages. Please wait.
---> Downloading header for galeon to pack into transaction set.
galeon-1.3.21-8.fc4.i386. 100% |=========================|  38 kB
00:00
---> Package galeon.i386 0:1.3.21-8.fc4 set to be updated
--> Running transaction check
--> Processing Dependency: mozilla = 37:1.7.8 for package: galeon
--> Finished Dependency Resolution
Error: Missing Dependency: mozilla = 37:1.7.8 is needed by package
galeon

The galeon package currently in Extras has been packaged to use mozilla
version 1.7.8 (and *only* 1.7.8, that's what the equals sign "=" means).
However:

[pfrields@localhost ~]$ rpm -q mozilla
mozilla-1.7.10-1.5.1

So there's the problem.  The galeon package wants mozilla version 1.7.8,
but 1.7.10 is what's on FC4 currently.  If you query Bugzilla for
information on galeon in Fedora Extras, you'll see a bug open for this
problem.  Expect resolution Real Soon Now.

I'm not sure how we can approach this in the yum tutorial, short of
getting into explaining RPM spec tags such as Requires:.  Let's not do
that.
