Ryan, Thank you very much for the tip.
I did as you suggested, and as evidence of it making the switch, when I invoke "python", I see that it's now 2.5.4: % defaults write com.apple.versioner.python Version 2.5 % defaults read com.apple.versioner.python { Version = "2.5"; } % python Python 2.5.4 (r254:67916, Jul 7 2009, 23:51:24) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> quit() However, when I run the AppEngine I still get the same result: % python /usr/local/bin/dev_appserver.py helloworld/ Traceback (most recent call last): File "/usr/local/bin/dev_appserver.py", line 60, in <module> run_file(__file__, globals()) File "/usr/local/bin/dev_appserver.py", line 57, in run_file execfile(script_path, globals_) File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/ GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/ google/appengine/tools/dev_appserver_main.py", line 65, in <module> from google.appengine.tools import os_compat The same happens if I use the AppEngine Launcher.
