I think that the haskell platform should use the current versions mtl 2.1.1 and transformers 0.3.0.0. We use these versions in the Gentoo Haskell overlay. Most stuff builds with these versions with trivial sed's or patches to relax the mtl and/or transformers dependencies. Please feel free (anyone, any distro) to use our patches/seds or to create your own based on these: https://github.com/gentoo-haskell/gentoo-haskell For example, in sci-mathematics/agda/agda-2.3.0.1.ebuild: epatch "${FILESDIR}"/${PN}-2.3.0.1-haskell-src-exts-1.13.patch epatch "${FILESDIR}"/${PN}-2.3.0.1-mtl-2.1.patch the patches are in the files subdir. In dev-haskell/haskeline/haskeline-0.6.4.6-r1.ebuild: src_prepare() { sed -e 's@mtl >= 1.1 && < 2.1@mtl >= 1.1 \&\& < 2.2@' \ -i "${S}/${PN}.cabal" || die "Could not loosen dependencies" } Thanks, Mark _______________________________________________ Haskell-platform mailing list Haskell-platform@projects.haskell.org http://projects.haskell.org/cgi-bin/mailman/listinfo/haskell-platform
