[Haskell] The Haddock documentation is not showing up on the Hackage

Hi, I uploaded a package named enchant on the Hackage last week, but the Haddock documentation is not showing up yet. The Status field says "Docs pending" and "Build status unknown". https://hackage.haskell.org/package/enchant-0.1.0.0 enchant uses c2hs as a build tool to generate the FFI binding and requires libenchant-dev to be installed on the machine. I wonder how I can tell these build requirements to the Hackage server. Regards, Kwang Yul Seo
