(There is no newer port for FreeBSD than 5.2.12)

server2# cat distinfo

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.
