xmlada must be installed with gprbuild
install libgpr with make libgpr.build / make libgpr.install (important) 
missing ocaml deps. nums & (one other)
cp gcc to gnatgcc or gprconfig gets confused
BUILD=DEBUG simplifies building gnatcoll 
GPR_PROJECT_PATH (but shouldn't be needed if xmlada is installed right?)

--with-libada
--enable-languages=c,ada --enable-multilib
x86_64-linux-gnu (not needed? the real issue was system gnatgcc confusing gprconfig)
