I forgot, I also tried tar-1.0 on GHC 6.6, and had the same problem
there.  Even after updating Cabal, there was no way to install
'bytestring' due to the conflict with 'base'.  A modified package
description for 'base' helped.

The reason that tar absolutely wants new stuff is 'instance MonadFix
Get', which is not in binary-0.3.  If you absolutely want users of GHC
6.6 to stick with binary-0.3, then you should provide a maintenance
release binary-0.3.1.  And we're back to Eternal Compatibility in
Theory...
