I've just run across a problem with my cabal build system -- I'm not yet sure if this is a cabal problem or a system configuration problem. I've been developing a package on OSX using the ghc 6.4.1 and cabal from darwinports. All is fine and dandy. However, today I've sucked my darcs repo down to my machine at home (running Gentoo linux) and now my package won't build. (this time with GHC 6.4.1 from portage and cabal 1.1.3) It halts while apparently running an Alex generated lexer through CPP, with the error: ghcconfig.h: No such file or directory My GHC install has this file at /usr/lib/ghc-6.4.1/include, but it clearly isn't in the include path that cabal is using. So the question is -- is this a cabal bug of some kind, or is the gentoo setup messed up some how? How should I proceed? Thanks Rob Dockins
