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

[Max Kuhn]

Everyone,

I have a few only versions in /Library:

drwxrwxr-x  4 root  admin  136 May 13 23:46 2.10
drwxrwxr-x  3 root  admin  102 Aug  9 16:00 2.11
drwxrwxr-x  6 root  admin  204 Aug  9 16:00 2.12
lrwxr-xr-x  1 root  admin    4 Aug  9 16:00 Current -> 2.12

I need to check that something worked in 2.11.x, but when I run

$  /Library/Frameworks/R.framework/Versions/2.11/Resources/bin/R64

R version 2.12.0 Under development (unstable) (2010-08-08 r52687)
Copyright (C) 2010 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

Note the dates on the 2.11 and 2.12 paths are both Aug  9 16:00, so
I'm guessing that the 2.12 installer over-wrote the 2.11 install.

I installed 2.11 again, did my testing, then re-installed with 2.12
pkg file dated today:

$ ls -al /Library/Frameworks/R.framework/Versions/
total 8
drwxrwxr-x  6 root  admin  204 Sep 15 12:19 .
drwxrwxr-x  8 root  admin  272 Sep 15 12:19 ..
drwxrwxr-x  4 root  admin  136 May 13 23:46 2.10
drwxrwxr-x  3 root  admin  102 Sep 15 12:19 2.11
drwxrwxr-x  6 root  admin  204 Sep 15 12:19 2.12
lrwxr-xr-x  1 root  admin    4 Sep 15 12:19 Current -> 2.12

It looks like it wiped out the 2.11 install again. I know that the
labels are "Under development" and "unstable", but it is worth brining
up.

The OS version is 10.6.4.

Thanks,

Max
