Apparently you're not successfully linking to libffi, which should
contain those ffi_* symbols.  What FFI-related options or environment
variables did you pass to ./configure?  I'd like to see the output of
"grep -i libffi config.log".

It also appears that Guile was configured with thread support, but that
your libgc was built without thread support.  If you don't need thread
support, then I suggest passing "--without-threads" to ./configure,
otherwise you'll need to rebuild libgc (preferably version 7.2d) with
thread support.

     Regards,
       Mark
