Hey all. I recently wanted to rebuild GHC 6.12.1 from source (from a downloaded tarball). After the first install from that source I went and updated Cabal (from a tarball grabbed from Hackage). When I now try to do a rebuild of GHC, I get this error compiler/main/Packages.lhs:233:63: Couldn't match expected type `InstalledPackageInfo_ String' against inferred type `Cabal-1.8.0.2:Distribution.InstalledPackageInfo.InstalledPackageInfo_ m' Expected type: [InstalledPackageInfo_ String] Inferred type: [Cabal-1.8.0.2:Distribution.InstalledPackageInfo.InstalledPackageInfo_ m] In the second argument of `map', namely `conf' In the first argument of `return', namely `(map installedPackageInfoToPackageConfig conf)' make[1]: *** [compiler/stage1/build/Packages.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [all] Error 2 (also here: http://hpaste.org/fastcgi/hpaste.fcgi/view?id=16380#a16380) I'm running the build like this: make distclean sh boot ./configure --enable-shared make -j 2 but (I'm guessing) it's looking at the already-installed Cabal libs and not liking what it's getting. Any ideas on how to get past this?
