Setting up emacs with rosemacs

edit

I followed the information for installing rosemacs but this has presented me with some problems. For starters, I didn't have a .emacs file so I created one from scratch (not sure if that's what is supposed to be done). I tried editing this file in both ways described but I keep getting errors.

Warning (initialization): An error occurred while loading /home/usr/.emacs':
File error: Cannot open load file, rosemacs
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the--debug-init' option to view a complete error backtrace.

I did exactly that, opening emacs in debug mode through the command line:

$emacs --debug-init

This yields the following in the scratch area once emacs is open:
