Oh, that's true, my system's Pyflakes is installed for Python 3.
But I'm wondering a bit, because my virtualenv is Pythpn 2 only.
And even after activating it, it seems that it is calling the global
Pyflakes:

Although my PATH got the virtualenv's bin directory at first position:

So it seems I have to call it like
> (env)$ ./env/bin/pyflakes dslrpicontrol
To get the right one?

Isn't it virtualenv's task to use the one from the environment?

Will do! Thanks!
