Description of problem:

The package rhnpush in Spacewalk contains program /usr/bin/solaris2mpm which needs pkgtrans, that one is not Required. So running solaris2mpm fails. We should either Require appropriate package (heirloom-pkgtools comes to mind) or not ship /usr/bin/solaris2mpm in rhnpush.

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

# type solaris2mpm
solaris2mpm is /usr/bin/solaris2mpm
# rpm -qf /usr/bin/solaris2mpm
rhnpush-0.4.6-1.el5

How reproducible:

Deterministic.

Steps to Reproduce:
1. Download package from http://www.download-ftp-center.com/sunfreeware.com/sparc/10/lsof-4.77-sol10-sparc-local.gz
2. Run solaris2mpm on that package.

Additional info:

I've originally built heirloom-pkgtools package to be used during build-time for rhn-solaris-bootstrap package. However, it looks like it could be used on Spacewalk servers (and even on clients that want to run rhnpush) during runtime as well.

The proposed solution is to add heirloom-pkgtools to Spacewalk 0.5 compose and Require it (or /usr/bin/pkgtrans) in rhnpush.
