Comment (by amosrobinson):

 Ok, fair enough. It would be nice if we could get it working without
 having to `make install` - I don't know about other people, but this is my
 method of having multiple versions of ghc to test against.

 Here's the output of otool. Not sure if it's of much help:

 {{{
 kallisti:t amos$ otool -L Main
 Main:

 }}}

 The other thing is, the only reason I started compiling with `-dynamic`
 was because I was getting errors about missing `.dyn_o`. Something about
 template haskell? I don't really understand.
