[MacRuby-devel] macgem & macrake take so much time to start ??

Hi I'm trying macrub & hotcocoa these days, and have a question, when i try macgem list or macrake (after `hotcocoa hello`),it take so much time to get a response,it just hang there ,and after almost a minute i see the `Hello from HotCocoa` window what's my problem ?? I'm using macruby 0.6 and SL 10.6.2
