[yt-users] Problem while installing YT with Rockstar

[Nathan Goldbaum]

The install script tries to build rockstar using conda-build. This is
failing somehow. Fortunately it isn't strictly necessary to use the install
script to do this.

Instead, you might try following the instructuctions to build yt with
rockstar support here:

http://yt-project.org/docs/dev/installing.html#installing-support-for-the-rockstar-halo-finder

One could also try modifying the install script to not use conda-build for
rockstar, as I doubt it's actually necessary.
