I've been having the same problem. I found some information on GPU mining X11 coins on the Astroid forums but couldn't figure out what the heck to do. Maybe you can figure it out. Or have you found a solution already?

https://github.com/elmad/darkcoin-cpuminer-1.3-avx-aes.git through ./autogen.sh and ./configure but make fails with a massive amount of errors like this:
