Downloading and installing VIM: Need help!

VIM is included with Mac OS X. No need to download or install anything -- simply launch the Terminal application, then type "vim" (no quotes) and hit enter.
Mac ships 6.2, I have downloaded 6.3, the default vim doesn't seem to have color syntax like the gvim version on windows has...
I am not sure how to go about this update. Any advice?

Thank you!
