Just adding in my experiences, I had the same problem with 4.2.2 and Apache2. Went out and got the latest code snapshot (php4-200208141800) and tried installing that, but that bombed out, different error, but roughtly the same place.
After poking around, discovered that the sapi/apache2filter/Makefile on the snapshot was missing info. Ended up using the 4.2.2 Makefiles, but copying the source files from the snapshot into the apache2filter dir. Thatt seems to have fixed the problem.
Can't want for 4.3 though 🙂
