When building ghc with the doc USEFLAG on, I get the following circular dependency error: Calculating dependencies... done! [ebuild N ] dev-lang/ghc-6.4.2 USE="X doc opengl -openal -test" [ebuild N ] dev-haskell/haddock-0.8 USE="doc" [ebuild N ] dev-haskell/cabal-1.1.6.2 USE="doc -profile" !!!

USE=doc emerge ghc # this might or might not trigger it if the issue is with haddock or cabal and they are already installed without the doc use flag, but at least so long as they get pulled in as dependencies, the problem occurs Actual Results: USE=doc emerge ghc These are the packages that would be merged, in order: Calculating dependencies... done!

Nothing we could do about it at the moment. *** This bug has been marked as a duplicate of bug 190671 ***
