Dependency version problem with Cabal

In my leksah.cabal file i have the package dependency Cabal >=1.6.0.1. When I have installed Cabal-1.6.0.2 as well a s1.6.0.1 I get the following warning: 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-1.6.0.1 package leksah-0.4.3 requires Cabal-1.6.0.2 Why does this happen, as leksah does not require Cabal-1.6.0.2? How can I solve this problem? Jürgen Nicklisch-Franken -- View this message in context: http://www.nabble.com/Dependency-version-problem-with-Cabal-tp22590000p22590...
