Add distcc 2.x to mports.  distcc is a frontend for gcc that allows one to run daemons on other hosts to "help" with compiling source code.  It has a gnome based gui for monitoring activity.

This might be useful for magus runs if we had a cross compiler setup for sparc64 possibly to "help".  Currently magus runs take over two weeks on that platform and we don't do it much as a result.
