This is actually fairly easy to fix, and it should be. Doing the gzip
in the installed man page area really trashes my /usr file system!!
After a make world I find that my /usr is usually fragmented >2%, before
it is under <.5%.
Also, I am of the opinion that the only thing being done during the
install phase is INSTALLING, not gzipping or otherwize munging files!
Almost to the point of having a ${PROG}.stripped rule (you'r cmp thing
in install is going to have to compare a stripped version of programs
or it will always fail for the standard binary case).
