Very, very helpful Chris; thanks; and thanks also to the many other helpful haskellers.
They have (hopefully working) cabal files to make compiling and installing ea\ sy.
Unfortunately, not so easy, for PCRE.regex. But hopefully this is just due to my ignorance and there's a simple workaround. At any rate, after darcs --getting as you suggested, I ran make, and got various complaints. I installed haddock, happy, alex, hat, c2hs, and cpphs with apt-get. But was unable to find a deb repository for greencard, the final requirement with apt-cache search. I then downloaded the latest version of greencard wget http://www.haskell.org/greencard/downloads/greencard-latest-src.tar.gz and ran sudo make install install-pkg It chugged along for a while, but finally errored out with ghc -package-name greencard -cpp -fglasgow-exts -fno-prune-tydecls -prof -c Foreign/GreenCard.hs -o Foreign/GreenCard.p_o -hisuf p_hi ghc-6.4.1: unrecognised flags: -fno-prune-tydecls I then googled, but found nothing for no-prune-tydecls or no-prune-typedecls (thinking it might be a typo) Anybody out there can help me get greencard working, so I (and all us perlers) can start using PCRE from haskell? thomas.

I think if you paste the subRegex code above underneath an "import Text.Posix.PCRE" declaration then you get what you are looking for.
To install:
The regex-* package hosting is via darcs and has been copied/moved to
http://darcs.haskell.org/packages/ (The stable regex-* versions) http://darcs.haskell.org/packages/regex-unstable/ (The unstable regex-* vers\ ions)
so "darcs get --partial http://darcs.haskell.org/packages/regex-pcre" might b\ e useful.
They have (hopefully working) cabal files to make compiling and installing ea\ sy. Note that regex-pcre and regex-tre need libpcre and libtre to be installed separately. regex-posix needs a posix library, but GHC already provides this package with a working libary.
