[Scons-users] CheckPkG on OS X 10.9

[Gary Oberbrunner]

Start with the SCons man page at
http://www.scons.org/doc/HTML/scons-man.html.  Right up near the top
you'll see examples of importing shell environment variables.  For
instance, to import PATH and HOME:

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

You'll have to do some legwork to figure out which env var(s) are key
for your problem; just divide and conquer.
