#906: cabal install cabal-install-0.10.2 fails due to dependencies ---------------------------------+------------------------------------------ Reporter: AndreasVoellmy | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ cabal install cabal-install-0.10.2 fails for me. The problem is that it depends on unix < 2.5 and versions of unix before 2.5 depend on base < 4.4. But base 4.4 is selected very early on in the cabal install. Later versions of unix (i.e. 2.5.0.0) work with base < 4.5, so it seems like this issue could be fixed by releasing a new version of cabal-install that works with unix 2.5. Here is the output from cabal install cabal-install-0.10.2 -v3 --dry-run: {{{ searching for ghc in path. found ghc at /usr/local/bin/ghc ("/usr/local/bin/ghc",["--numeric-version"]) /usr/local/bin/ghc is version 7.2.1 looking for package tool: ghc-pkg near compiler in /usr/local/bin found package tool in /usr/local/bin/ghc-pkg ("/usr/local/bin/ghc-pkg",["--version"]) /usr/local/bin/ghc-pkg is version 7.2.1 ("/usr/local/bin/ghc",["--supported-languages"]) Reading installed packages...
