I'm trying to re-compile ghc 6.11 and it doesn't find parsec.

The ghc build system is fairly self contained. I'm not sure if it cares if your bootstrapping compiler has parsec or not. If the ghc build system is looking for the parsec modules then I very much doubt it is going to be looking in any parsec package that your bootstrapping compiler might have registered (either globally or per-user). It'll be looking for the sources that it comes bundled with. A quick look in my ghc source tree reveals: ghc/utils/ext-core/Language/Core/ParsecParser.hs ghc/libraries/parsec/Text/ParserCombinators/Parsec.hs The first one, utils/ext-core is importing parsec. Is that what you're trying to build? The parsec package is an extralib so wouldn't be present unless you did ./darcs-all --extra get If you can't get the ghc build going try asking on the ghc users mailing list. Give as much detail as you can about what you did so people can give you more helpful advice. Duncan
