namebench crash at Lion

Build namebench on Lion 10.7.4 and Xcode 4.3.3. When starting, namebench is crashing. Starting from Terminal and the message in the Terminal is:

    print "Starting up on Python %s [%s] compiled with %s" % (platform.python_version(),

I can't reproduce this, FWIW.

This error message means something went wrong while running the main python script, but provides no insight about what went wrong. I encountered this unhelpful message several times while working on resolving #40859.

Prior to r112865, the port was using the system's python, so possibly something is amiss with your system python. As of r112865, the port now uses MacPorts python. If you see the problem again now, you can tell python to run the script on the command line to see what error is occurring. For example if you're using the namebench port's python27 variant, you could run:

python2.7 /Applications/MacPorts/namebench.app/Contents/Resources/main.py

The error message "No Info.plist file in application bundle or no NSPrincipalClass in the Info.plist file, exiting" should indicate that everything is fine and that the program will work correctly if you double-click it in the Finder; a different error message would be something we could investigate the cause of.
