* Zapping/VLC/MPlayer: use libXv.
* MPlayer: upgrade to 1.0pre4.
* Zapping: add libXext to the rpath. I don't understand why this is
necessary. Zapping doesn't itself link against libXext, though some
of its dependencies do. (Maybe this is due to `--export-dynamic'?)

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
