This actually doesn't have anything to do with the currently installed
hoopl package, it's related to the hoopl package tucked away in the
libraries directory.

If you do a fresh checkout of ghc-ios you wind up with too new of a
version of libraries/hoopl.  The fix is to checkout the
remotes/origin/ghc-7.4 branch.

The same applies to libraries/directory and libraries/process.

I'm maintaining a script to keep this all straight:
