I, too, would like to run multiple versions of R, via command line, on Mac OS X. 
I have looked in vain for a clear explanation of why there can be one and only 
one 'Current' version of R running at a time.

After running the installer, I manually edit the 
/Library/Frameworks/Versions/<version>/Resources/bin/R script.
Replacing the '/Library/Frameworks/R.framework/Resources' with 

Is this sufficient to support multiple versions of R on a Mac?
