Hi all, If you're following the progress of cabal-install this is a heads up. I've switched it over to using this new InstallPlan stuff. So the dependency resolver is now expected to produce a valid install plan. The conditions for validity are quite strict and the current weedy dependency resolver is often not able to make a valid install plan. It is particularly bad with dependencies on inconsistent versions of packages, especially if the already installed packages have such inconsistencies. So watch out for these and report the most common ones and we can think about how to improve the resolver. It does produce fairly detailed error messages describing the problems with the install plan. There's a bit more work to do to make the dep resolver pluggable. I suspect it's not working with hugs at the moment again (producing valid install plans when you've no idea what's installed is more than a little difficult). Duncan
