Actually, I was thinking more like:

#!/bin/sh
# standard easy_install comment lines here
""":"
exec '/path/to/python' "$0" "$@"
"""
# rest of the code here

The idea being to preserve the inspectable info that easy_install 
puts in the first few lines of script comments.  And of course, to 
properly pass through sys.argv, etc.  The path to sys.executable also 
needs to be properly escaped by the code writing the script.
