Description of problem:
I launch redhat-config-packages in a terminal, then I select a package
to add. After the program automaticaly add packages in order to
satisfy dependencies, it tries to install the first package and I got
the message:

The file /mnt/cdrom/RedHat/RPMS/modutils-devel-2.4.25-13.i386.rpm
cannot be opened. This is due to a missing file, a bad package, or bad
media.

Version-Release number of selected component (if applicable):
redhat-config-packages-1.2.6-1

How reproducible:
Always

Steps to Reproduce:
1. Open a terminal as root
2. redhat-config-packages

4. update system
    

Additional info:

To correct this bug, I modified:

/usr/share/redhat-config-packages/GroupSet.py
/usr/share/redhat-config-packages/method.py

by replacing RedHat/RPMS by Fedora/RPMS
