That is bizarre; Python should not be touching /bin/ls at all (if you're at all familiar with POSIX, 'ls' is the "list contents of directory" command). I'd be more inclined to suspect that your XCode has been corrupted somehow; perhaps reinstalling that might help. I wouldn't expect LLDB to depend on Python either, but who knows.
I don't think your installation of Python 3.3 is at fault here, since as you noted the error is dealing with Python 2.7. I believe that's simply the OS built-in Python. You might try opening up a commandline in Terminal and running this: /Library/Frameworks/Python.framework/Versions/2.7/bin/python which ought to run the 2.7 Python REPL (read-eval-print loop, a simple program that lets you test out Python code). If that fails, then your OS built-in Python has probably been damaged. Hope that helps. -Chris On Mon, Apr 8, 2013 at 12:06 PM, Boyd Collier <bcoll...@mail.sdsu.edu>wrote: > Hello All, > > In late February, I thought I'd give python a try, so I took steps to run > it on my Mac.
