So this would be what I did. (except that the PKGREVISION
bump is superflous)
There is a minor flaw with my changes to buildlink/options
stuff: The option "firefox" would match an installed
firefox-2.x, but otherwise building against firefox2 is
tested. Are you going to commit that too or should I?
