Looks like you are running one of those GNAT distributions where the 
compiler driver for gnat is gnatgcc instead of just plain old gcc. This 
has caused more problems with builds like this. perhaps you can do 
something with export CC=gnatgcc before the configure. The basic problem 
is that (I think) configure does not know how to find gnatgcc, it is 
looking for a gcc that knows Ada.

What host OS is this?
