I don't think you can ruin anything if you install any extra files in 
your local tree (rather than the global teTeX tree).
I have some packages that I copied over from other machines and 
simply created a
hierarchy inside my Library folder.

The unix path is something like ~/Library/texmf/tex/...

(using the Finder, open your home folder, then the Library folder inside it.
Successive create a folder, name it "texmf" then open it and inside 
create another new folder and call it "tex". Then place anything you 
need inside that (subfolders are ok, and even recommended to keep 
things organized).
