This probably means that you have packages installed in your ~/.cabal

avoid this problem you can configure cabal to put built packages into a

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-different-folders-for-32-bit-and-64-bit-package
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.
Cheers,
Simon
