Yes, I mentioned this in my announcement here.

Is there a good tutorial to learn about pip? Everything I've seen so far
seems to be of one of two extremes, either:

"pip is awesome, just run 'pip install packagename' and it cannot fail!!!1!"


"oh, pip did the wrong thing again? you can fix that by standing on one leg,
sacrificing a goat to the Great Old Dark Ones, deleting these files, or
possibly some other ones, and if the phase of the moon is exactly right it
will behave as you want..."

I know that pip is Officially The Best Thing Evar, but my experience so far
has been less than satisfactory.
