When you run "open foo.app" from the command line, your shell  
environment is passed in to the application; when you double-click in  
Finder, a default environment is passed in, modified by ~/.MacOS/ 
environment.sh.

Make sure that your startup script sets all the environment variables  
your app needs before exec-ing your program.
