# haddock-2.4.1 also deps on the upgradeable package dev-haskell/filepath.
# however, it's included in >=ghc-6.8.2, so we use the core package without
# stating the dependency in DEPEND.
# ghc-6.8.2 has filepath-1.1.0.0
# ghc-6.10.4 has filepath-1.1.0.2
# we bundle the dep on ghc-paths to reduce the dependencies on this critical
# package. ghc-paths would like to be compiled with USE=doc, which pulls in
# haddock, which requires ghc-paths, which pulls in haddock...
# bundling ghc-paths forces us to depend on >=cabal-1.6 rather than >=cabal-1.2
