Presently, mod_fastcgi doesn't compile with Apache 2.2. I've
tracked down a patch which makes it work correctly, and inserted
it into this port.
In the process, I have converted the port to use the new
USE_APACHE knob, simplifying the Makefile enormously.
Fix: Here's the patch. I've added one new file, files/patch-apache22
and I've removed pkg-plist (it's no longer required).
