I updated the ruby gems and now I keep getting this error when trying to run: ruby script/server
dyld: NSLinkModule() error dyld: Symbol not found: _rb_thread_alive_p Referenced from: /Users/mikejahn/.gem/ruby/1.8/gems/fastthread-1.0.5/ lib/fastthread.bundle Expected in: flat namespace
Trace/BPT trap
any suggestions on how to fix it?
