   problems with xCode... Directory not found
  I'm getting the following warning when I compile my program:ld: warning: directory '/Users/alex/Library/Frameworks' following -F not foundDoes anybody know what causes this error, and ideally how to fix it?I'm pretty sure that it started after I updated xCode via the automatic update (xCode 3.2.2).Normally I wouldn't worry about it too much, but I'm having a problem rendering in opengl (via SDL), and I want to make sure that it's not because of some linking error.Thank you
