no, cabal-install does not automatically install build-tools at all, only Cabal checks them for compilation. I guess the reason is that build-tools needs to be put on the PATH, and that is beyond the scope of cabal-install.
This is rather sub-optimal. One place where people are running into this problem is when installing Yesod. Yesod depends on warp which depends on bytestring-lexing which requires alex at build time. The problem is that many of the people trying out Yesod are newcomers to Haskell. They are going to try "cabal install yesod" and have it fail because alex is missing. This is not a good introduction Haskell/Yesod. Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo http://www.mega-nerd.com/
