In particular the ebuild must list all the dependencies of the package. Required Haskell libraries are listed in the "build-depends:" field in the cabal file, so that one is easy. However it is not clear how to find out the build tools that the cabal package requires.
For example packages may require alex or happy or c2hs or other build time tools. Is there any better way to find if these tools are needed than to look through the source tree for any files with the appropriate extensions ".y", ".x", ".chs" etc?
And a similar follow up question is how do cabal packages specify dependencies on particular versions of required tools? For example they might depend on some feature in the latest version of a tool. Duncan
