I may not need shared libs, so this may is a suitable workaround for me.  
However, most of my configure parameters were copied from macports ffmpeg-devel 
port file.  They build it as a shared library, so I imagine they probably don't 
use gas-preprocessor, which sucks for macports users.

Yeah, I started port install gcc47, it will take a while to build. I'll install 
binutils 2.21 after that's done, and try again.

Thank you,
     Pavel.
