Hmmm, well I'm not sure I can help you with the installation - I do my installations the old fashioned way, by copying an existing good installation :-)

Here is a quick reference guide (http://zoo.cs.yale.edu/classes/cs210/help/emacs.html) I found about how to use it once you have it installed.

Actually, here (http://www.cs.utah.edu/~alee/emacs/emacs.html) is a great explanation about installing emacs I just found.
