 {{{
 7.3.1. Propagating PATH From the External Environment


  You may want to propagate the external PATH to the execution environment
 for commands. You do this by initializing the PATH variable with the PATH
 value from the os.environ dictionary, which is Python's way of letting you
 get at the external environment:


         import os
         env = Environment(ENV = {'PATH' : os.environ['PATH']})


  Alternatively, you may find it easier to just propagate the entire
 external environment to the execution environment for commands. This is
 simpler to code than explicity selecting the PATH value:


         import os
         env = Environment(ENV = os.environ)


  Either of these will guarantee that SCons will be able to execute any
 command that you can execute from the command line. The drawback is that
 the build can behave differently if it's run by people with different PATH
 values in their environment--for example, if both the /bin and
 /usr/local/bin directories have different cc commands, then which one will
 be used to compile programs will depend on which directory is listed first
 in the user's PATH variable.
 }}}

 So... yet another completely braindead broken by design build system.
 It's up to each project to decide that it should honor the build
 environment?!?
