2.7.2 compiled on os x 10.3.9 now how do I get R to run by just typing R

I have compiled R 2.7.2 on mac 10.3.9 and can run it within an xterm
window.  I compiled it with the --without-aqua so I am only using x11.
 I don't have access to the x11 device within the terminal window, but
it does work when running R from within x term.

if I move into this directory:
cd ~
cd /Library/Frameworks/R.framework/Versions/2.7/Resources

and then type
.
/R

R starts up- how do I get it to work from anywhere with just issuing
the command R at the command prompt.  Thanks for your help,

so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
