It's possible that sys.executable could also start with /System if you  
use a pythonw shell script.

[crack:~/src/stackless/Stackless] bob% pythonw -c "import sys; print  
sys.executable"
/System/Library/Frameworks/Python.framework/Versions/2.3/Resources/ 
Python.app/Contents/MacOS/Python

[crack:~/src/stackless/Stackless] bob% python -c "import sys; print  
sys.executable"
/usr/bin/python

[crack:~/src/stackless/Stackless] bob% python -c "import sys,os; print  
os.path.realpath(sys.executable)"
/System/Library/Frameworks/Python.framework/Versions/2.3/bin/python

I guess it should be changed to  
os.path.realpath(sys.executable).startswith('/System')
