FPS package dependency in GHC 6.4 and GHC 6.6

[ghc@…]

When switching from GHC-6.4 to GHC-6.6 I must remove all FPS dependencies in Cabal, which is not only very annoying, but seems to be unnecessary. I understand that ByteStrings? are now integral part of the GHC package, but why can't there be an FPS package, maybe a dummy package, that must be imported for using ByteStrings?? Remember that this is not only about switching from 6.4 to 6.6: I have different machines with different versions of GHC, thus I have to work with both versions simultaneously.

You can make an empty fps package and install it on your ghc 6.6 machines if you so wish.

It's too late for us to do anything about what ghc 6.6 comes with now.
