Finding options for ports

[Kill the Penguin]

I've ran into this sort of problem from time to time. How do you find and
specify options in those ports that don't present a banner. For example,
the php4 port has many options listed in the Makefile.ext file, but it's
not clear how to turn these on. I looked through the ports docs again and
I don't see anything like "make showoptions". Can someone give me a clue?
