[R-SIG-Mac] upgradeable R layout

[David Winsemius]

I am attempting to follow this set of directions and am hung up. I  
will trim the original message and describe what I have done so far:

The installation of the Tools is the sticking point:

I am attemptng to follow the directions at http://r.research.att.com/tools/

Checked Xcode and finding that it was 3.0 and seeing that 3.1.1 was  
available, download and installed  a 1GB file. Checked to see that  
Xcode.app had been updated.

Downloaded and installed the gfortran package from the ATT website.

copied "export PATH=$PATH:/usr/local/bin" to Terminal line.

Followed "Tools on CRAN" link:

devpack4-darwin8-bin4.tar.gz was download via Firefox to /Users/ 
Downloads/ and automatically expanded to a folder with Library and usr  
descendants within /Downloads/ which I think is not the correct  
location. The contents of Library were apparently destined for / 
Applications/Frameworks/R.framework/Resources/ so I dragged the  
fontconfig file there.

Viewing the world through the Mac Finder it is unclear where the /usr/ 
local folder contents are supposed to go. There is probably a Unix  
command that will safely copy the contents of the /usr/ folder  
currently residing in /Downlaods to where the "true" /usr/ folder  
resides. So I opened a Terminal window and typed:

cp  /usr/local/

Can I now just type:
cp /Users/davidwinsemius/Downloads/devpack4-darwin8-bin4/usr/local/* .

... and get all those new files put in the corresponding descendant  
folders?
