Installation question:

The import pylab
command reports an error. See bold below for details. What
installation step(s) am I missing?

Thanks!

It looks like you're using the gtk backend but you're running on a remote terminal without an X11 connection. That's what "could not open display" probably means. Are you logged in remotely by any chance? Does 'python -c "import gtk" ' work?

If you want to run headless, you can use the "Agg" backend. See here:

it looks like you've got GTK set as your default back-end, but are not running and X-server on this box.

If you want to use MPL without a GUI, you need to set your default backend to "AGG", but you probably shouldn't use pylab for that anyway, but rather use the OO API -- some googling will tell you about that.
