[Fedora-haskell-list] Building haskell-platform 2010 for F12

Dear all,
    Given that F13 is just around the corner I should probably just
upgrade.  However, as a learning exercise I've been building the F13
haskell-platform packages on F12.  Ghc from the F13 ghc.spec builds
correctly and produces
ghc-6.12.1-5.fc12.i686.rpm	ghc-ghc-6.12.1-5.fc12.i686.rpm
ghc-ghc-doc-6.12.1-5.fc12.i686.rpm
ghc-libs-6.12.1-5.fc12.i686.rpm
ghc-doc-6.12.1-5.fc12.i686.rpm	ghc-ghc-devel-6.12.1-5.fc12.i686.rpm
ghc-ghc-prof-6.12.1-5.fc12.i686.rpm
ghc-prof-6.12.1-5.fc12.i686.rpm

In order to build cabal-install I require ghc-HTTP which depends on
libHSnetwork.  I can't seem to find libHS* spec files in koji or
http://cvs.fedoraproject.org/viewcvs/rpms/

Could someone point me towards this spec file?
