I only have access to windows at the moment and I'm getting a weird linker
error in bindings-GLFW when trying to build GLFW-b:

Loading package bindings-GLFW- ... linking ... ghc.exe: unable to
load package `bindings-GLFW-'
ghc.exe: warning: _vsnprintf from msvcrt is linked instead of
unknown symbol `strdup'
Failed to install GLFW-b-1.4.6

I'll try on osx tomorrow.
