Hey Sling-Shot,
it is not recommended to use your day-to-day system for packaging, either reserve a spare computer for this or even better install VMWare or Virtualbox and perform the building there. The reason is that during testing and installation of development packages (lots, and lots, and lots) your system can easily become unstable,
I recall there was a packaging guide somewhere when I started out as packager, don't know the status of this - but a very nice introduction to packaging - eventually try and search/google after an introduction to RPM packaging for PCLinuxOS,
your first step should be to setup a virtual environment or a spare system, then read all the sticky threads (one is about setting up vmware btw.) in this section (packagers),
report back then ;-)
have fun :-)
