This probably means that you have packages installed in your ~/.cabal from a 32-bit GHC and you're using a 64-bit one, or vice-versa. To avoid this problem you can configure cabal to put built packages into a directory containing the platform name.
How does one do this? I ran into this problem a while ago and couldn't figure it out: http://stackoverflow.com/questions/12393750/how-can-i-configure-cabal-to-use...
I do this at work where I share the same home dir between several different machines, and my .cabal/config contains install-dirs user prefix: /home/simonmar/.cabal bindir: $prefix/bin/$arch-$os -- libdir: $prefix/lib libsubdir: $pkgid/$compiler/$arch-$os -- libexecdir: $prefix/libexec -- datadir: $prefix/share -- datasubdir: $pkgid -- docdir: $datadir/doc/$pkgid -- htmldir: $docdir/html -- haddockdir: $htmldir Hope this helps.
