If you either convert path to a dict or have avoid_paths_in_environ() return a 
dict you can do:

+            output = subprocess.check_output(". %s > /dev/null; %s;" % \
+                (self.tc.sdkenv, cmd), env=path, shell=True)

It's not quite obvious in the docs that you can pass that in, they refer you to 
the Popen docs.
