Hmm, this doesn't happen on windows... I'll try it on wxGTK 2.5.1
to see what happens.

I never thought about this. In the case of shared libraries, you
are definitely right and we should generate two versions. However,
I can now (in cvs head) link with static wxWidgets libraries, so
I think that I can always support openGL in wxHaskell (as
libwx_gtk_gl.a is linked in statically) -- the only question that
remains is whether the application will load the system openGL libraries
on demand or requires them to be present? (in the latter case, we
need to provide two versions too).

I am not to eager to provide two different versions of wxHaskell,
so we should test first whether static linkage will work for us.

Thanks for mentioning this,
All the best,
  Daan.
