FWIW, this

$ gnatmake hello \
-largs -lgnala -L/Developer/SDKs/MacOSX10.4u.sdk/usr/lib -lblas -llapack

_nearly_ works with an unedited i-forbla.adb GNAT-GPL-2007 on Mac OS X Tiger;

opt/gnat-gpl-2007-dynamic/lib/gcc/powerpc-apple-darwin8.11.0/4.1.3/adalib//libgnala.a(a-nlcoar.o) reference to undefined _zdot_

So the ugly linker options involved finding libblas and liblapack only.
