b) putting Gtk2HsSetup.hs in either gtk2hs-buildtools or any other library means that ./Setup.hs has to run to realize that this library is missing and that it needs to be downloaded. However, ./Setup.hs cannot be run because it imports Gtk2HsSetup.hs which is not yet available.
There is MIN_VERSION_<package>(), so you might be able to check whether it is defined/has the right version, if it comes with the tools package.
Does that work in Setup.hs? I thought that these CPP macros were generated by the 'confgure' step, which may not have been run yet.

But, if the setup library is part of the tools package, and the latter becomes a dependency, wouldn't cabal install take care of that bit?

I don't know if (b) can be solved by e.g. conditionally importing Gtk2HsSetup.hs if it is there and only installing libraries and re- invoking Setup.hs one this is done. This is a common trick in Makefiles, e.g. one could call make recursively to first build dependencies. Any suggestions welcome.
