That's cabal's very odd way to tell you that you don't have a base >= 4.2 
installed (and it can't get you a new version of base, since that's really 
baked into the compiler).

Yes. And it requires Cabal >= 1.8, since the Cabal API changed.
However, the only changes to the previous versions were edits in the cabal 
files and one Setup.hs, so

cabal install wx-0.12.1.2 wxcore-0.12.1.2 wxdirect-0.12.1.1

has good chances to work on 6.10.*
