I have been using the Energia IDE on my MacBook Pro for the Launchpad.
As I understand it, it is an Arduino variant, free and open source:
I am not sure if it will run on the XO, but it is an option as I see it.

I look forward to hearing about your progress. I will share whatever I
learn as well.

> Currently Arduino, PIC, and LegoWeDo are being used with the OLPC XO with the programming being done on the XO, either in TurtleArt or Scratch. The electronics of the robotics kits are being used as I/O expanders. The students are not programming the processors on the robotics kits. (I am not sure what LegoNXT is doing).
