Description of problem:
When attempting to install cups, cups-drivers, and the cups-drivers-hpijs and
cups-drivers-pnm2ppa modules onto a clean system,
the installer attempts to install the cups-drivers-* packages
before the cups package. This leads to errors, when the post-install
scripts of these packages attempt to restart CUPS:

cups: unrecognized service

Version-Release number of selected component (if applicable):
cups-drivers-{hpijs, pnm2ppa}-1.1-0.20020313.3

How reproducible:
Always

Steps to Reproduce:
1. If necessary, remove cups, cups-drivers, cups-drivers-hpijs, cups-drivers-pnm2ppa
2. rpm -ivh cups-drivers-hpijs-1.1-0.20020313.3.i386.rpm \
  cups-drivers-pnm2ppa-1.1-0.20020313.3.i386.rpm \
  cups-drivers-1.1-0.20020313.3.i386.rpm \
  cups-1.1.14-15.i386.rpm

Actual Results:  cups-drivers-hpijs and cups-drivers-pnm2ppa were installed
*before* cups, and an error "cups: unknown service" was produced each time.

Expected Results:  cups should have been installed before cups-drivers-hpijs and
cups-drivers-pnm2ppa.

Additional info:

The cups-drivers-hpijs and cups-drivers-pnm2ppa do not Require cups, but they
have a dependency on cups.
