Note that both ghc-6.10.1 and the current darcs version of the
ghc-6.10.x branch come with base 126.96.36.199. See:

There's something else going on. cabal-install does know about the base
package but does not have any hard coded versions. The only constraint
it places on base is that the dependency solver must pick an installed
version of base (ie and not try to install from sources off hackage).

We'll need more details to work out what the problem is. Could you
describe the symptoms in more detail. See also if ghc-pkg check reports
