Here's a problem variations of which have been plaguing the Haskell
community for as long as I can remember.
To see it for yourself:
1.) Be running OS X
2.) install GLFW-b-1.0.0 (you may need to cabal update) [1]
3.) ghci -package GLFW-b
4.) import Graphics.UI.GLFW as GLFW
5.) GLFW.init
Security camera footage of the crime in progress:

One of the first things GLFW.init does on OS X is
... = [[NSAutoreleasePool alloc] init];
That causes
-[NSAutoreleasePool init]: unrecognized selector sent to instance ...
which seems to mean that NSAutoreleasePool doesn't understand the "init"
message/method. But [[NSAutoreleasePool alloc] init] is really basic
stuff.
What is going on?
