Normally this is farily easy to do, with cabal configurations. (See
bytestring's .cabal file for example). However, the binary internals
changed in such a way that it wasn't worth preserving backwards
buildability. Instead, you should use binary 0.3 with ghc 6.6 libs
A released version of bytestring 0.9 will be on hackage shortly.
