1. Make MASTER_SITES entries contain a trailing /. Garrett says that
assuming a '/' seperator between entries in MASTER_SITES and entries
in DISTFILES is a dangerous assumption. This will also be taken
out of bsd.port.mk.
2. General clean-up. Some of these Makefiles were a little grim.
Make sure they're all in sync with the sometimes rapidly changing
bsd.port.mk! :)
3. Some small configuration tweaks to keep them compiling under the
most recent 2.0 - some things seem to have broken along our road
to release.
