             Bug #: 11661
           Summary: set-xcode-analyzer fails if Python 2.7 is installed
           Product: clang
           Version: 3.0
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: e28eta at yahoo.com

This is with checker-258, on OS X 10.6.8.

I have python 2.7 installed as a dependency of something else through MacPorts.
When I run set-xcode-analyzer, it fails with an import error:

$ ./set-xcode-analyzer 
Traceback (most recent call last):
  File "./set-xcode-analyzer", line 9, in <module>
    from AppKit import *
ImportError: No module named AppKit


Searching the web for this particular error or to find the download for AppKit
fails, because it apparently comes bundled with the OS. I finally found it with
a `locate`

I don't know the best way to solve this. I changed the first line of the script
to run python2.6 instead of python, and that worked for my machine. I don't
think the same fix would work for everyone.

Maybe just some documentation that users need to use a python that came bundled
with their OS? Or a way to detect and print a helpful tip to the user when the
script fails?
