bcfg2 client does not install YUMng packages if they are provided by other packages

[https://www.google.com/accounts/o8/id?id=AItOawn0s7RDAZJqmy8qhaS8PFtgoke6VxxZKSI]

We provide LPRng packages for our RHEL6 workstations, which also have cups installed due to dependencies. The LPRng and cups packages we build are:

# yum list LPRng cups
Installed Packages
cups.x86_64                      1:1.4.2-44.el6_2.3                     @updates
Available Packages
LPRng.x86_64                       3.8.28-3.caen.el5                       bcfg2

When bcfg2 runs, it fails to install LPRng even though we specify it as a package to install in the configuration. Here is what we see in the debug log:

LPRng appears to be provided by:
  1:cups-1.4.2-44.el6_2.3.x86_64
Verifying: LPRng-None-3.caen.el5
  Not checking version for virtual package

and the LPRng package is not installed. Now, if I ask yum to install it on the command line, it doesn't have a problem:

# yum install LPRng

Complete!

Now, in the debug log, I see:

Verifying package instances for LPRng
Verifying: LPRng-None-3.caen.el5

I find the "None" part rather odd here, but I haven't figured out why it's failing.

What I do suspect is that the VerifyPackage? function in the YUMng.py Tool just automatically verifies the LPRng package no matter what, because it determines that it is a Virtual Package. Cups gets installed as normal, and the cups package claims to provide LPRng:

# rpm -q --provides cups|grep LPRng
LPRng = 3.8.15-4

Now, LPRng 3.8.28-3 is newer than 3.8.15-4, so it really should be allowing LPRng to be installed. Bcfg2 seems to see any package that claims to provide the package name to pass through VerifyPackage? as verified, and does NOT perform any kind of version checking.

Also, seeing the "None" in the version in the debugging log makes me wonder if something about the package object in the YUMng plugin is getting things confused.
