This should not be done pretty soon IMHO. It is fairly hard (sometimes
impossible) to tell whether one version is bigger than the other.
Furthermore such deps would not be a big gain right now; you just get
the error message earlier. (sorcery would not be able to up /
downgrade required spells properly).

That would not work (without a special check for gcc version deps in
sorcery which are independent from the other version checks). gcc and
gcc2 are completely different spells which install different stuff to
different places.

Right now the biggest step forward would be a stable sorcery. We
should get 1.0 done and tested before we go after new major features.
