don't USE_IMAKE, don't appear to change behaviour on NOMANCOMPRESS (many
do, subtly) and don't install more than one manpage.
Any port listed here is a good candidate for a general review simply
due to age... For example, a number of them seem to patch an install:
target into the program Makefile and/or arbitrarily compress their
manpages from patches/patch-*. This has been out-of-vogue since I would
guess mid-1996, at least.
