gnat-gpl-2009 has gcc 4.3.4. So no wonder things don't work well; it is
best to use the same version of gcc for all language compilers and the
final linker.
There's not much gprbuild can do to help here, except reject all
versions that don't match exactly, which is what it's already trying to
do.

So you only have dylib files for gnat 4.4.3, and they are in a fairly
canonical location; that explains why gprbuild finds them when
Toolchain_Version is plain "GNAT".
This is a packaging bug in the GNAT GPL 2009 Darwin distribution; it
should include the dylib files.
You are mixing gcc versions, so it's lucky they work, and you probably
will encounter more subtle bugs at some point.
Since you have g++ 4.4.3, and gnat 4.4.3 with dylibs, I suggest you use
just those two, not GNAT GPL 2009. Build gprbuild from source using gnat
4.4.3, then QtAda with that.
I'm not clear on darwin9 vs darwin10; I gather that's the operating
system version. I guess you are currently running darwin10, and the
darwin9 stuff is left over from before an upgrade? If things are mostly
upward compatible, using the darwin9 stuff may be less problematic than
mixing gcc versions.
