Bug 508988

system-config-network uses rhpl for a few things, some of which are only ever used by rhpl.  We are trying to drop rhpl for Fedora 12, so you'll need to move those bits into system-config-network itself (rhpl.iwlib and rhpl.ethtool)

The translation bits should be relatively straightforward to replace with something like:
  import gettext
  _ = lambda x: gettext.ldgettext(domain, x)
  N_ = lambda x: x 
except for the fact that you're overriding __builtins__["_"] which you really can't do with this pattern as you can't always know what the domain is going to be.
