If anyone out there is in need of a project - working on this is something that could really benefit MacPorts (not only for the buildbot, but it would be really cool if we could get it to the point that it was always used when configuring/building ports. On end-user machines it would fix most of the problems we sometimes see where ports built on an end-user system end up having problems due to linking with random libraries in /usr/local or picking up unexpected dependencies from other installed ports).
