missing a word in "how to contribute to django"

[bjb@…]

In master, 1.7, 1.6 and 1.5, on page ​https://docs.djangoproject.com/en/1.6/intro/contributing/#installing-git,
in the second sentence of the second paragraph it says:

If you get messages saying that this command could be found

and it should say

If you get messages saying that this command could not be found

I have made this change in my github fork of django: ​https://github.com/bjb/django

on master, stable/1.5.x, stable/1.6.x and stable/1.7.x .

​https://github.com/bjb/django/tree/stable/1.5.x
​https://github.com/bjb/django/tree/stable/1.6.x
​https://github.com/bjb/django/tree/stable/1.7.x
