Yes. Android Builder will not work under cygwin. I don't know that it ever will. That's on the TO-DO list, but it's so far down that it's not on the posted TO-DO list.
I've only tested under Xubuntu 10.04 and minimal Ubuntu 10.04.
If you happen to work it out on cygwin, let me know! I'm sure others would be happy to have the option. Heck, I might even be. I'm mainly using Ubuntu because of AB anyway. (Although, it is kind of growing on me.)
