Problems on FreeBSD with 4.2.0 and Apache 2.0.35

I've been trying to get PHP working on Apache 2 on FreeBSD. I started out using the ports tree, but 4.1.2 and Apache 2.0.35 don't seem to agree on the API for the "bucket brigade" stuff. So I hacked the mod_php4 port to use 4.2.0 instead of 4.1.2. That failed because Apache wasn't compiled with threads. So I added WITH_THREADS to the apache port build and rebuild 4.2.0. Now if I have the AddModule active for php4, Apache hangs before forking off all of the prefork children (but sometime after creating all of the listen sockets). If I comment out the AddModule line for php, everything works (except, of course, php). Anyone else have this combination working?
