Hi Greg:

Use the Python Package Installer Plugin!

Note the "If you already have a cluster running that didn't originally include the PyPkgInstaller plugin in its config you can manually run the plugin on the cluster ..." at the end.

Let us know how it goes.

Subject: Re: [StarCluster] Configure Nodes to submit jobs

Hi everyone,

I found the bug. Apparently I library I installed in Python is only
available on the master node. What's a good way to install Python
libraries so it's available on all nodes? I guess virtualenv, but I'm
hoping for something simpler :-)
