Wow! What an active list!! :)
Let me answer all in one:

Oh! I understand now. Sorry for calling it a bug.
The problem is that I found MANY times problems with dependencies under
epoch: a package A is build over version 1:... of package B that contains
the file C. Then it appears version 2:... with a different (or missing)
file C, yum tries to upgrade to the 2:..., but then there is a missing
dependency trying to upgrade B because file C needed by A. This is a
usual problem when mixing repositories.

Perhaps. But I found this problem with some packages that were never
fixed.

Finally I understand what is this all about. Good.

Missing Dependency: libpisock.so.9 for package: libmal
Missing Dependency: libpisock.so.9 for package: kdepim
I suppose libpisock.so.9 is contained in 1:0.12.0-0.pre4.5.2.1
and not in 2:0.11.8-12.4.fc5.

I solved it excluding pilot-link, and uninstalling gnome-pilot.
Too bad...
But then, what to do in such a case? If I understood correctly,
the only solution is uninstalling some packages, or excluding the
update (in this case, of pilot-link)?
Thanks a lot!!!
