Dependency version problem with Cabal

In my leksah.cabal file i have the package dependency Cabal >=
When I have installed Cabal- as well a s1.6.0.1 I get the following

Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
package ghc-6.10.1 requires Cabal-
package leksah-0.4.3 requires Cabal-

Why does this happen, as leksah does not require Cabal-
How can I solve this problem?
