[Haskell-cafe] Checking dependencies from C packages in cabal

Hi, all, When pkg-config info is not available for a library (when I could use pkgconfig-depends), what should I use to check if needed libraries are installed and to give the compiler all needed info about include files and library location? Also, is it possible to do that without configure and make files? I have no experience with them. I also tried reading the Distribution module, but wasn't able to recognize what could be a natural way to handle this problem. Thanks, Maurício
