Yes, unfortunately, Cocotron only compiles on OS X. However, I borrowed a friend's older MBP for a weekend to get a feel for the system. He already had the Cocotron stack on there. Fun. Fun. Fun. Same friend bought a Western Digital 1Tb drive for $100 and installed it into his MBP. It worked great until that drive went sour. Then, the replacement went sour. Third time's a charm, right? :-D
