[R-SIG-Mac] Rscript?

[Roger Koenker]

I have:

yzzy: pwd
/Library/Frameworks/R.framework/Versions
yzzy: ls -la
total 8
drwxrwxr-x+ 16 root  admin  544 Oct 20 11:13 .
drwxrwxr-x+  8 root  admin  272 Oct 20 11:13 ..

drwxrwxr-x   3 root  admin  102 Oct 20 11:13 3.3
lrwxr-xr-x   1 root  admin    3 Oct 20 11:13 Current -> 3.2

but note that my Rscript expects that there is a bin directory here...
