Not sure how you are going to grab the libs for FreeBSD though without possibly CVSup'ing the source, which I'm not saying is impossible-just a minute pain. So, in essence I may have been a bit too pessimistic about the task. I didn't really get into the subject of distcc though I suppose and should have read a bit more in-depth articles earlier. I was just exploring instruction sets for compiling via the similar architecture for a LAN distcc farm, but gave up after realizing there were far too many clients with differing archs from my own, and the benefit wasn't worth my time since it was all for charity. -Garrett
