I installed it yesterday and had three "moments" when I thought things  
had gone wrong, none of which proved to be enduring problems.  During  
the install process using the downloaded bundle from the ATT site I  
noticed that the progress bar had stopped for what seemed to be an  
unreasonable period and realized that I had a running instance of R.  
Quit()-ting appeared to allow progress to resume. (So my first bit of  
potentially glaringly obvious advice would be to shutdown all  
instances of R before the install. I couldn't find this bit of advice  
on the Install directions but it is certainly possible that the  
authors thought to too obvious to mention.)

The next puzzle was when I checked the installation of the R.app and  
R64.app GUI's. I assumed (wrongly as I eventually figured out) that  
they would have a more recent date than 2009 when viewed in the  
Applications folder. It turned out that they should (still) be version  
1.35 and that the new ones looked just like my old ones and work just  

The third "moment(s)" was when reinstalling package rms and dependent  
packages. I first tried installing the binary versions from my CRAN  
mirror and nothing seemed to be happening in hte time frame to which I  
have been accustomed. I "Force quit". I then restarted and installed  
from source. There was a very long period of no console activity, but  
I couldn't see any burning need to "Force quit" and I went away and  
came back 10 minutes later, to find the compliation process begun and  
then watch it run throught o completion and notice of success. Looking  
up at the intial portion of the console massages I discovered that  
about 20 packages were installed, so my initial impatience cause me to  
prematurely interupt what was probably a normal pause for the packages  
to be downloaded.

Normal behavior seems to have been restored after a few temporary  
moments of cluelessness on my part.
