[Haskell-cafe] Packaging Haskell Environment for Mac App

I would recommend avoiding anything related to pkgs or installation of any
kind, what you really want is a relocatable (and read-only!) .app bundle
that you can put wherever you want and it just works. The annoying part, in
general, is making sure that nothing has hard-coded paths and for dynamic
library references the install name is relative rather than absolute. The
actual building of an .app bundle is a matter of putting a few files in the
right place and creating an Info.plist file for the metadata.

The next (far more annoying and perhaps not really feasible) step would be
trying to make it work sandboxed so you could distribute it in the app
