That's the literal view of Derek's post, and it's completely naive one.
The opposite view is just as unhealthy - seeing yourself as the constant victim; it will equally get you nowhere. Civers is not a dumb enough guy to advocate either of these extremes.
It's about creating a mindset that enables you take to take more action in dealing with your own problems. Expanding your own view of your sphere of influence to its maximum potential.
TL;DR - the view isn't solely about anyone's fault, or some strategy of how to dole out blame; it's about maximising your own ability to make a difference.
But it's not about the initial worldview (i.e the title of the post), but how it enables you to view things, and act on them, in consequence.
Striving to take more action on the things you care about is practically never a bad things, and that's what Derek is wanting to achieve, not single-handedly shoulder the entire world's problems by claiming himself the sole contributor of all of its events.
A pythonist would just say:
"I just install a python environment from virtualenv, git clone an app and type 'pip install -r requirements.txt' and then its all working."
virtualenv ~= rbenv, and pip ~= bundler.
Either set of the two make it easy to install appropriate packages for separate projects.
Now maybe the googleability of this knowledge isn't as great as it could be, but ask any good pythonista and they'll set you on the right track.
