Somewhere on this long line you mentioned libaunit1-dev
depending on GNAT 4.4; the package says it depends on
ada-compiler.  Actually, AUnit v.1 indeed only needs an
Ada compiler, no fancy configuration, Ada 95 should do.

Debian Sid says, ada-compiler is provided by either gnat-4.4,
or by gnat-4.6.  Is any of these installed?  It might be
useful to install them if only to keep the Debian
package system consistent, even when a different GCC
should be used for compiling. That seems wasteful, but
is an easy way to deal with the necessarily complex
bureaucracy.

If ada-compiler in Debian will typically mean GNAT,
and there is a matching installation of GCC 4.x of yours,
but then there are complaints about missing gnat-4.4 or gnat-4.6,
you may be working with Debian packages but outside Debian's
package dependency system.

With AUnit in particular, there are easy ways to handle
the situation.

IIRC, the original v.1 of AUnit was modelled such when
v.2 was out, many asked for the original model, hence v.3.
So, for worldly needs, v.1 might be the thing you want anyway.

v.1 of AUnit is portable, pure Ada. For use with GNAT,
it has been sufficient in the past to put a GNAT project
file in some convenient place, or use one's own directories,
or not use a project file at all!  Just make the files
accessible to the compiler.  (AUnit v.1 came when there
was no project configuration description language yet.)

Producing a package system compatible translation framework
is more work.
