<div>Are you using gcc from Xcode or Macports? I've had trouble using the macports compilers with YT, but the Xcode gcc 4.2.1 works with my macbook air 11" OSX 10.7.4. If you have stuff installed from macports maybe try disabling macports and then install YT to see if it works? Just have to take out /opt/local/bin from PATH variable.<br>
