Is there some sort of bundle that you can use to install cabal-install easily? Because it looks to me like I'd have to spend the better part of an evening manually downloading and installing the gazillion of dependencies it has, which is far too much work when I just wanted to spend ten minutes playing with some package...

You typically need HTTP and zlib. Perhaps cabal-install could have it's own minimal implementations to be standalone? However I don't find needing to cabal build and install 2 packages to be so difficult. And once you have cabal-install, you've got it ;-) It should be able to update itself. Maybe adding cabal-install to the ghc packaging solves all the problems, then they just need zlib and http in the main distribution. Dave

Hi guys:

I don´t know how difficult really is, but it seens that it could be done because all the necessary elements are there (except perhaps the mapping package name-hackage url): Why hasn´t been done yet Is unknown to me. It would be very useful and a big save of time to have a cabal commad

"chech-dependencies-and-install-them-by-downloading-them-from-hackage-then- configure-build-and-install-this-package?. The unix installers do is t from binaries and are obsolete, so I have to do it manually with cabal everytime when i download a new compiler version from haskell.org.

Cheers Alberto.

Use cabal-install:

cabal update && cabal install foo

checks for dependencies, downloads and builds them automatically (if possible).
