Use a sandbox to compile the cabal-install executable: $ cd cabal/cabal-install $ cabal sandbox init $ cabal sandbox add-source ../Cabal $ cabal install --dependencies-only && cabal build And then copy it to somewhere in PATH: $ cp dist/build/cabal/cabal ~/bin/cabal-1.18 > Are there any catches to having multiple Cabal libs installed or will > the latest one always be used if not specified? Yes, the latest one is always used. _______________________________________________ cabal-devel mailing list cabal-devel@haskell.org http://www.haskell.org/mailman/listinfo/cabal-devel
