I've built gnugo for the iLiad, but the GUI frontend is taking a little bit longer. The backend was fairly easy to get running once the cross compile issues were worked out with the pre-processing that has to happen. Details on the build are
on my wiki. CGoben is not happy about interfacing via gmp with gnugo, so I'm looking for other front ends.
Attached is the (large) binary for gnugo which you can play via ssh or rxvt. You will also need to install libncurses into /usr/local/lib or /usr/lib on the iLiad. If you have the OE tree from iRex it is in /usr/local/arm/oe/arm-linux/lib/libncurses.so.5. Don't forget to run ldconfig on the iLiad after installing it.
