[Orgmode] Install orgmode alongside older version?

[Uriel Avalos]

I'm running NTemacs. I thought it was a "bleeding" edge version but it is 
apparantly running an old version of orgmode (5.03b). How can I install the 
latest version? Can I follow the official docs? The docs seem to assume that 
orgmode is *not* installed on your system. If I add a load-path, will that 
overwrite the old orgmode installed on my system?
