An easier solution is to modify the file outputp.c and raytrace.c so the
program produces ppm files (for the pbm+ package).  It took me about 5 
minutes.  All you need to do is modify the routine(s) that write the header
in outputp.c so it is a legal ppm header ("P6 <xres> <yres> 256"), and change 
the loops in raytrace.c to go top to bottom instead of bottom to top.  Voila.
It might get a little stickier if you use the Linda multi-processor stuff.
