Compiling Haskell X11 bindings

Hello everyone, I've been trying to improve the Haskell X11 bindings so they're more usable. So I tried to compile with my changes, and here's the output: rob@TheRing ~/programming/src/darcs/X11 $ runhaskell Setup.hs configure configure: creating ./config.status config.status: creating config.mk config.status: creating X11.buildinfo config.status: error: cannot find input file: include/HsX11Config.h.in How can I remedy this? I'm looking forward to seeing my changes in action! Thanks, Rob Hoelz
