This change seems reasonable to me.  If you want to test the corner-case 
that the old preinst/postun logic was added to handle, try the following:

    1.  Install a Haskell-flavored RPM that uses the new install scripts.

    2.  In the spec file for that RPM, bump the Release (but leave
        everything else the same) and rebuild the RPM.

    3.  Update (rpm -Uhv) to the new release of the RPM.

    4.  Check to see that the package is properly registered w/ GHC.
