I had the same error, so finally didn't use the enable-x264 switch.
I assume, that some of the libraries to compile x264 are broken at least
on FC5 :-(
It will compile without the x264 switch and you can still create mp4
files which will run on your ipod.
Using a syntax such as
ffmpeg -i file.mpg -f mp4 -vcodec mpeg4 -maxrate 1000 -b 700 -qmin 3 -qmax 5 -bufsize 4096 -g 300 -acodec aac -ab 192 -s 320x240 -aspect 4:3 file.mp4
should create ipod compatible videos.
However you most likely will then run into issues with the myth2ipod scipt.
I figured, that the called nuvexport will create wrong switches and causes ffmpeg to crash with a floating point error.
I tried to modify the nuvexport code, but wasn't quit successful yet.
