What, if anything, stands in the way of parallelizing Cabal installs, make -j style?

Parallelizing ghc --make

Unless Louis meant what's stopping cabal-install from installing dependancies in parallel instead of serial? In which case; nothing?

I think cabal-install compiles Setup without starting ghc or such (I may be wrong). This would be fixable. If you want to volunteer try hack-nix. It's based on the Nix distribution system which provides this feature natively. You can even ask others computers to help building dependencies quite easily. Downside: At the moment it will pull all depndencies (including kernel headers and glibc..) if you install it on a common linux system. Marc Weber
