Comment #5 on issue 363 by allbery.b: non-positive argument error on NVidia Xinerama set http://code.google.com/p/xmonad/issues/detail?id=363 As I understand it, cabal doesn't currently deal with updates and dependency checking because it's too easy to get into "diamond dependency" issues. (Package A updated, package B's deps specify old version, package C's deps either specify new version or default version, package D tries to use packages B and C => bad things happen; the only way to prevent this "automatically" would be to refuse to allow package A to be updated at all, and if package D is installed later it must refuse to allow the install until someone fixes the dependency conflict manually.) -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
