On my system, it has been, and (looks for some time) will remain in my /ports/devel subdir. try the binaries on ftp://tns.csusb.edu/pub/unix/pentium/xv and mpeg_play. they might be a little old, but do some "benchmarks" on them against the latest pgcc compiled mpeg_play and xv. :) In my opinion, (John,David,and Bruce will most likely agree) pgcc compiled kernels are very dangerous to say the least. <> -Rob Mallory [rmallory@csusb.edu]
