It may come from the version of GHC you're using (Cabal version is fixed for one specific GHC version). Which one is it?

I'm using ghc 7.4.1 (from the Ubuntu Precise repository). Don't know if this is relevant but ghc-pkg list tells me that I have: /var/lib/ghc/package.conf.d Cabal-1.14.0 directory-1.1.0.2 process-1.1.0.1 ... Mike.

Did you install the haskell-platform package? What is the output of ghc-pkg check?

Hey that fixed it! (Removing ~/.ghc.) Thanks! Mike.

Reality is less simplistic than that. .ghc has library metadata. .cabal has library files. See my http://www.vex.net/~trebla/haskell/sicp.xhtml and verify, verify, verify. Since GHC simply trusts its metadata (and not re-scan library files to re-discover libraries), metadata dominates. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
