I use PICPRG just fine with a similar programmer(with 3 Vpp lines)
I just reconfigure the software to toggle whichever Vpp line I need 
to use for a particular chip in the configuration screen.

I may have also changed the code so that unused bits in the parallel port
are set correctly, depending on if you're using an inverting or
non-inverting buffer, to make sure the other Vpp lines are always off when
not in use. (But I don't have the code with me so I can't tell you exactly
what it was, if I made any change it was pretty simple in the lowlvl.c file)
