Right. It does that on purpose and with good reason.

Do you think the error message could be improved? The message should already say
that it detected ghc 6.8.2 but that it requires ghc 6.8.1 (or 6.6.1).

Yes. The .hi files are versioned and ghc will reject .hi files created by a
different version of ghc.

You could probably trick the installer but it would not help you at all, as all
you'll get is ghc reporting that the .hi files were written by ghc-6.8.1 rather
than ghc-6.8.2.

You are in luck however, I did a build with ghc-6.8.2 just the other day but
hadn't announced it yet:
http://haskell.org/~duncan/gtk2hs/gtk2hs-0.9.12.1.exe

Let me know how you get on, though in general bugs are best reported to the
gtk2hs-devel mailing list or in our bug tracker.
