What pogramming app to use?

I am new to his list and to using a Linux box to develop code for the 
PIC processors.
I have been getting everything together, gpasm, gputils, etc, but I have 
really confused about a tool to download code to the PIC via either 
parallel or serial ports. I plan to first use LVP on the parallel port 
(using 16F873), then maybe build a high voltage ICSP at a later date.

I found picprg, but it states 2.4 kernel and I had a problem building 
it. It complained about:
lowlvl.c:113:24: error: asm/system.h: No such file or directory
make: *** [lowlvl.o] Error 1
and before I started looking for that fix I thought I would ask about 
any newer/better solutions.

Thanks,
tj
