I get this as well. The cause is that gcc is still at 4.3.4, while
gnat is at 4.4.3; gprconfig tries to find an Ada runtime for 4.4.3 by
searching in the gcc directories for 4.3.4 (which is a little odd, but
it works if everything is consistent).
Ludovic: this is similar to the gcc problem I had before, but that's
fixed; any suggestions.
In particular, this works in my unstable schroot that has gcc 4.4.2 and
gnat 4.4.2 installed.
You can see this in detail if you run gprconfig -v -v.
The question then is; why is gcc still at 4.3.4, when gnat-4.4 directly
depends on gcc-4.4? Here's what 'aptitude show' says:

I get this in the schroot as well. I'll see if I can debug it.

Yes. GNAT GPL 2009 does not have this bug; gprbuild 1.2.0 is based on
GNAT GPL 2008.

Actually, it seems to be a problem with the gcc version dependencies.
I will leave my main system broken for the moment, in case someone has
a debug/test suggestion. In the meantime, can you verify what version
of gcc you have, and try to get it truly upgraded to gcc 4.4.2 to see
if gprconfig works then?
