[R-SIG-Mac] Installing 2.11 while keeping previous version

[Richard Friedman]

Dear List,

	I want to install R.2.11 for Mac while keeping my previous versions  
(R.2.9 is the most recent.).
I am running Mac OS X 10.5.8.

On the installer the following note appears:

Note: By default the installer upgrades previous Leopard build of R   
if present. If you want to keep the previous Leopard build, use
pkgutil --forget org.r-project.R.Leopard.fw.pkg

Here is what happens when I try the command

[richard-friedmans-computer:/usr/sbin] friedman% ./pkgutil --forget  
org.r-project.R.Leopard.fw.pkg
No receipt for 'org.r-project.R.Leopard.fw.pkg' found at '/'.

  In the past I used to remove R-Framework.pkg from Library/Receipts  
but I am not sure that this will work
this time.

Thanks and best wishes,
Rich
