I have a small comment...

You will also want regex-compat if you want to keep the old Text.Regex module 
API.  (Renaming Text.Regex.New to Text.Regex)

I have just gone over the stable repository [1] for regex-base,posix,compat and 
tweaked the cabal files to better match the packages they actually depend upon. 
  The latest version of these is now 0.71

But I suspect you don't use cabal to build these for GHC.

The posix c library is slow, but at least it is what people have been using. 
Note that Text.Regex.New from regex-compat is so close to Text.Regex that it 
shares the same "bugs", such as splitting or substituting with a pattern that 
matches an empty string and going into an infinite loop.

Should I sacrifice a little backwards compatibility and catch these "bugs"?
