Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: samplesContrib- (user goal)

[__3] next goal: wxcore:setup.Cabal (dependency of wxcore)
[__3] rejecting: wxcore:setup.Cabal- (constraint  
maximum version of Cabal used by Setup.hs requires <2.6

> cabal --version
cabal-install version
compiled using version of the Cabal library
