Overhaul the port before I attempt to make it more usable on modern FreeBSD:
- Switch to official "previous version distfile + patch" scheme instead of
using our apparently hand-rolled distfile; it is also in line with what
most GNU/Linux folks do
- Remove superfluous assignment of PKGMESSAGE, it's done automagically
- Cleanup sed(1) expressions in REINPLACE_CMDs, prefer contextual addresses
to hardcoded line numbers, remove useless global modifiers, etc.
- Pad pkg-message text display in post-install with blank lines to bring port
behavior in line with that of package
- Utilize OPTIONS, define LICENSE (GPLv2), adjust COMMENT
- Remove unneeded patches, add a patch which brings manpage fixes
- Install extra documentation
- Generally cleanup Makefile while I am here
