I am fiddling with the gentoo package livecd-ng which is supposed to be able to create a custom boot cd with arbitrary packages included (ie distcc). I can see now why it is in the "unstable" branch of gentoo - it doesn't work"out of the box", but I seem to be getting somewhere with some help from forums.gentoo.org. Will report back later.
If this works we should be able to boot all the distcc server machines off identical cd's and there should be no problems with gcc or library version differences. N
