[R-SIG-Mac] Previously installed versions after installing 2.12

[Simon Urbanek]

Max,

please consider reading the R for Mac FAQ (most notably 12.15) and the information displayed as you install R. The latter tells you that the default is to remove your old version and instructs you how to install multiple versions in parallel if that's what you want. The former explains why you need to change the "Current" version softlink if you want to switch between versions and there is even RSwitch app for that to be had at http://r.research.att.com

Cheers,
Simon
