The only instance of this behaviour that I know of involves using that
version of cabal-install with ghc-6.10.1.
The older version of cabal-install goes into an infinite loop when using
ghc-6.10, when it is presented with two installed versions of the base
package (and one depends on the other). In version 0.6.x cabal-install
was updated to understand this situation.
Are you absolutely sure you are using ghc 6.8 and not 6.10?

If you're using ghc 6.10 then the solution is to update to cabal-install
0.6.x. If you're quite sure you are using 6.8 then the bug is unknown.
It may still be worth trying upgrading to cabal-install 0.6.x.
