This is an excellent idea, and one I ultimately ended up using. However,
I've found that the ports infrastructure really doesn't tolerate
creating arbitrary categories, so I had to put a VALID_CATEGORIES+= bit
at the top of each of my ports' makefiles to get it to work without
patching any tracked files.

Another good suggestion. I find annoyance in that devel/glib20 (among
others) requires all of Perl and Python at runtime just to service two
script files that appear to be used only for certain compilation
options. It tends to bloat the embedded images that I build.
