I've used CPP, something like:
( export contents of Paths_magic ) where
mock implementation of paths magic here
Then in your .cabal file declare the define which causes it to use the
real magic paths module. When not compiling via cabal, you'll at least
have something sensible (like the current directory or something).
I'm pretty sure I didn't make this up, but I have used it. It's a bit
of a pain to set up, though.
