I’ve read the Simple Guide to Cabal at http://katychuang.com/cabal-guide/ http://katychuang.com/cabal-guide/ It says: create a copy of a package by running the command cabal install Some flags can speed up this process --only-dependencies -jN to build N packages in parallel --dry-run to see what cabal plans to do (recommended) But here’s the thing (piping a word count from —dry-run) $ cabal install hakyll --dry-run | wc -l 97 cabal install hakyll --only-dependencies --dry-run | wc -l 96 So it takes 20+ minutes to install a package that you just want to check out for a few minutes, while your CPU melts down in the process? I must be missing something here…? Thanks again for your newbie support, greatly appreciated. P.J.
