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  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"?
