I've noticed that quite a few of the Makefiles in /usr/ports have the
MASTER_SITES pointing to freefall.freebsd.org, which I find quite odd
since freefall doesn't have an anon ftp login. Most of these do not have
alternate sites listed which then requires the Makefile to be hand edited
to point to the valid archives at there local freebsd mirror before make
install will do anything useful...
