I have no experience with Ada however the general fix is to generate
"config.ads" at "make" time so that $prefix variable will be expanded.
in C you can achieve that with CPPFLAGS:
AM_CPPFLAGS = -DPACKAGE_LOAD_PATH=\"$(moduledir)\"
With other language this has to be done differently, you can use 'sed'
or 'config.status' in your Makefile. More details are provided in the
Autoconf manual [1].
