I'm not a 100% sure, but I think the way you're setting the ENV var is a 
little too late. The dictionary of environment variables has to be 
available at the time when all the Tools are detected and 
configured...and this happens in the call of the Environment() 
constructor. So you should rather try:

   env = Environment(ENV = os.environ, variables = vars)

instead. If all you need is the "PATH" variable, you can use:

   env = Environment(ENV = {'PATH' : os.environ.get('PATH','')}, 
variables = vars)


Best regards,

Dirk
