RHEL 5.3 and rpmdevtools

[Jon Stanley]

Not sure if this is the right place to bring this up, but attempting
to install rpmdevtools on a RHEL 5.3 beta machine fails because of a
file conflict - /usr/lib/rpm/check-rpaths-worker is now included as
part of rpm-build, and need not be included in rpmdevtools.

Fun thing is this is obviously an incompatible change - on RHEL
version <= 5.3, it's there, but > 5.3 it's not.  Not sure how to
handle this in EPEL-land..
