If you really need i386 this isn't going to help...

Is there any reason why you cannot rebuild libvpx from sources?  I think
libvpx will default to the x86_64 target you need if configure is run
without arguments.  If not, you probably just need:

/path/to/libvpx/configure --target=x86_64-darwin10-gcc

Then the usual make/sudo make install will work (or tell ffmpeg where to
look at configure time, if you don't want to install).
