Good suggestion -- I forget about logs too often :-/.
Here are the relevant parts from config.log:
configure:26532: checking for x264_encoder_open in -lx264
configure:26567: gcc -o conftest -g -O2 conftest.c -lx264 -lpthread -lm -lm

So it would appear that the x264 library is found, but one particular
part is not. A bit of searching suggests this happened to other people
too, and that some managed to solve it -- although I don't yet fully
understand how (I'm not really a programmer):
http://www.linuxquestions.org/questions/linux-newbie-8/problem-with-enable-libx264-option-in-ffmpeg-822156/
Anyway, I'll work on this some more as soon as I have the time.
Thanks for your suggestion,
Best regards,
Richard Rasker
