Package: gnat-4.4 Version: 4.4.2-4 I had gcc-4.4 (4.4.1-3) and gnat-4.3 installed. I upgraded to gnat-4.4, but it was non-functional, complaining it could not find system.ads. The problem turned out to be a missing symlink, that is installed by gcc-4.4 (4.4.2). The root cause is that gnat-4.4 depends on gcc-4.4 (>= 4.4.0-6); this should be changed to >= 4.4.2. -- -- Stephe
