[yt-users] Iteration Problems

[Matthew Turk]

As a quick note, I have recently been notified that the installation
instructions in the documentation instruct users to grab yt-1.5's
install script.  This was my error, and I apologize -- it seems to
have affected both BrianC and another user as well.

I'll be updating the docs as soon as I have a new build, hopefully
today or tomorrow.

There will be a point release of yt very soon (today or in a few days) if you want to wait for that. There are a whole slew of changes between 1.5 and what's coming, which will be outlined in the announcement email. If you feel up to switching now, you can do that inside the yt-1.5 directory like this:
