Hum...

Best I can think of is to take the hint (from Simon Urbanek) and move the .pkg 
file from Downloads and into another folder before installing. Some system 
cleaner-upper or virus checker could be moving stuff around. You haven't 
perchance some virus scrubber running which might be restoring your executable 
directories to a previous state?

You might want to make a note of the location and ownership of installed files, 
like in

Peters-Air:R pd$ ls -l `which R`
lrwxr-xr-x  1 root  wheel  47 Jun  6 17:41 /usr/local/bin/R -> 
/Library/Frameworks/R.framework/Resources/bin/R
Peters-Air:R pd$ ls -l /Library/Frameworks/R.framework/Resources/bin/R
-rwxrwxr-x  1 root  admin  9196 Apr 21 23:47 
/Library/Frameworks/R.framework/Resources/bin/R

and then, if/when it stops working, see if files have disappeared or changed 
owner or permissions.
