IR-GTS-BW Release in RAM - NDS Research & Development Posted March 23, 2011 I'm having the same issue as this man. And yes, I only have Python 2.7 installed. I think I found the problem. My computer has only Leopard, not Snow Leopard, so I think there may be a problem with Terminal not being a new enough version. I tried it on my brother's MacBook, which has Snow Leopard, and now it works perfectly.
