I should note that you do not need to edit the .cabal file to do this. As of Cabal-1.4 there are extra command line flags to configure (or equivalently to cabal install)
--extra-include-dirs=dir --extra-lib-dirs=dir

I have seen the new cabal arguments. All I was giving was debugging advice on a platform I have never tested on. And regex-posix has a very "old school" Setup.hs file with a small addition:
#!/usr/bin/env runhaskell
-- I usually compile this with "ghc --make -o setup Setup.hs"
import Distribution.Simple(defaultMainWithHooks, defaultUserHooks) main = do putStrLn msg defaultMainWithHooks defaultUserHooks
msg = "This links to the standard c library version of regular expressions.\n\ \The corresponding c header file is regex.h and there is a chance you\n\ \will need to edit the end of the regex-posix.cabal file to find the\n\ \include directory and/or library.\n"
Hmmm...the next version will probably need to mention the cabal command line flags as well.
