title: Can't execute python scripts, permission denied?
body: <p>I'm trying to compile a project using "appcelerator" (crossplatform dev for iphone/android). Just evaluating it. It seems to run some python scripts to do the build, but can't get it to work (and not getting anywhere on the help forums there). Seems like a permissions error, but I can't figure it out. Thought I'd try here in case this is a familiar thing in python:</p>
  
  <pre><code>Exception occured while building project:
  Traceback (most recent call last):

  <p>I've set the permissions for "run.py" and "builder.py" to 777. The "subprocess.py" file also is 777. I'm still getting the permission denied error. Is there something obvious I'm missing here? I'm an admin user, on os 10.6. </p>
  
  <p>Thanks</p>
