Dear People

I have an iMac 2013 with a Fusion Drive and OSX 10.8.5. No plans to migrate to Mavericks yet.

I have had issues also with x11 that I've solved with a "direct" install:

installer -pkg ~/Desktop/XQuartz.pkg -target / -allowUntrusted -store

But, when I try to install R-2.11.1 and above (I'm using R-2.10.1, and works well ;) ) I get the following message from the installer:

R 3.0.2 for Mac OS X 10.6 or higher (Snow Leopard build) can't be installed on this disk.
This build of R requires MAC OS X 10.6 or higher.

If I try from the Terminal

sudo installer -pkg ~/Desktop/R-3.0.2.pkg -target /

or:
sudo -s
installer -verbose -pkg ~/Desktop/R-3.0.2.pkg -target /

I receive this output from terminal:

installer: Cannot install on volume / because it is disabled. 
installer: This build of R requires Mac OS X 10.6 or higher

And it fails.
What can I do? Delete some plist? Regenerate something? Reinstall Mountain Lion? I really prefer to not to have to rebuild from source.

I have had no issues installing R on my notebook with Lion.

Regards
MW
