This looks closest to right if your extra libraries are installed in
/usr/local/lib and the corresponding headers are installed in
/usr/local/include.  I don't think you should have to add -fPIC to
LDFALGS or CPPFLAGS.

If libraries are not found, the place to look for clues is config.log.

Are there no binary packages for most of these components for your OS?
