Is there maybe a different package in world that depends on <=gnat-gcc-4.1.1? Anyway, you may want to look at --debug output to get a clue why it wants to downgrade. > Oh, and ~dev-lang/gnat-gcc-4.1 as RDEPEND in virtual/gnat does not > work at all (just, as I understand, it should not)). It should work, but it's not the same as the dep you stated above: it would match gnat-gcc-4.1-r1, gnat-gcc-4.1-r2 and so on, but not gnat-gcc-4.1.1, gnat-gcc-4.1.2, ...
