[FFmpeg-user] Determined to not find libvpx

[Andoru]

Sorry if this is "noobish" problem, but I followed this compiling guide for
Debian: http://trac.ffmpeg.org/wiki/UbuntuCompilationGuide 

I went through it entirely, making sure I get all the paths right, but
ffmpeg doesn't seem to want to find libvpx.
Here's config.log:

I've checked the log and there is indeed 
~/ffmpeg_build/includes/vpx/vpx-decoder.h and all the other include files,
so I have no idea what went wrong.
