Description of problem:

The rhel-instnum package is not Required by any other and when it is not installed, systems cannot register to Spacewalk server.

Version-Release number of selected component (if applicable):

Spacewalk 0.3

How reproducible:

Deterministic.

Steps to Reproduce:
1. Install Spacewalk on RHEL 5.
2. rpm -e rhel-instnum
3. Try to register system.
  
Actual results:

# rhnreg_ks --server http://server/XMLRPC --username admin --password xxxxx --force
An error has occurred:
While running 'registration.welcome_message': caught
exceptions.KeyError : 'xmlrpc'

See /var/log/up2date for more information

and on the Spacewalk server, there is

RHN 28698 2008/12/12 15:12:16 +02:00: ('Error importing xmlrpc: No module named instnum',)

in /var/log/httpd/error_log and

2008/12/12 15:12:16 +02:00 28698 10.34.34.139: server/rhnImport.load('ERROR', 'Error importing xmlrpc: No module named instnum')

in /var/log/rhn/rhn_server_xmlrpc.log.

Expected results:

We should not be able to install Spacewalk without the rhel-instnum package. In another words, someone ought to Require that thing.
