(There is no newer port for FreeBSD than 5.2.12)

I've tried using FreeBSD-6.4, 7.2 and 7.3 - all fresh installs. From the
ports tree install php5-ffmpeg, which installs ffmpeg from ports as
well. No errors during compilation. After installation is complete
simply executing php -v will result in a core dump, doing php -m clearly
shows the module loaded. Tried re-ordering modules in extensions.ini
file as well. Running ffmpeg via cli works fine. If you're using
Apache22 it will restart ok, if using Apache-1.3.x it will fail to
restart - yet leaves no error messages in logs or running thru gdb httpd
-X.
