It's not you who's doing something dumb, it's Apple:-)

_environ is defined in crt0, which means you don't have access to it in 
shared libraries or bundles. The workaround is to call _NSGetEnviron() 
to get at the environment pointer, see Modules/posixmodule.c for a way 
to do this in one place in your code that will make _environ available 
to all the rest of your shared library (or bundle).
