It looks like a bug in gnatmake and/or gnatgcc.  I've built and 
installed all three versions of gnat from ports, and all three versions 
install the normative environment library as libgnat.a.  It shouldn't be 
possible to build too many working programs without correctly linking to 
libgnat.a, so I'm curious as to what's going wrong to trigger this error.
