Hi Jeremy,

you were right, that did the trick. I also had to add 'gstreamer' as a
build input. Without that package the build wxGTK failed to produce the
media sublibrary -- but it failed silently and kept on building
regardless. Duh!

Anyway, NixOS now has the latest version of wxHaskell. Thank you for
your efforts.

I noticed, by the way, that wxHaskell doesn't compile with GHC 7.2.2:
