These ports currently obtain the unzip port dependency by setting 
USE_ZIP, and then everything just works, i.e. there is logic in 
bsd.port.mk to handle things like distfile extraction.

If we have to special case ports to deal with variant zipfiles that 
cannot be processed by /usr/bin/unzip then it gets messier because we 
have to account for some ports being satisfied with USE_ZIP=yes meaning 
/usr/bin/unzip and some still requiring /usr/ports/archivers/unzip.  I'd 
prefer not to have to add those workarounds.
