You either need to use subprocess.PIPE, or change "import subprocess"
to "from subprocess import *". If you take the latter approach, you
need to remove the "subprocess." prefix from subprocess.call,
subprocess.Popen etc.

The "import <module>" syntax requires you to use qualified names,
while "from <module> import *" allows you to use unqualified names.

Alternatively, you can import specific identifiers, e.g.:

	from subprocess import (call, Popen, PIPE, STDOUT)

In any case, the call:

            self.out = Popen(cmd, shell=True, stdout=PIPE, stderr=STDOUT).communicate()[0]

seems to work once the relevant identifiers have been imported.

BTW, GMConsole.runCmd() currently executes the command twice; once
with call(), and again with os.popen().

Also, I had to remove an "import images" statement from wxgui.py; that
module doesn't appear to exist.
