Quite so, but bundling everything that is not part of Apple's MacOS X  
distribution into the binary framework makes building source packages  
easier not more difficult.

Again this is my point.  As many source packages as possible should  
build with the binary R distribution without the users needing to  
understand the process.

I don't see this.   Nothing I suggested would stop you writing  
scripts.  MacOS X Tiger comes complete with Perl, Python and Tcl/Tk,  
but the only things installed under /usr are minimal wrappers or  
symlinks that invoke code in Frameworks or other subdirectories of / 
System/Library.  Indeed the only thing that a binary install of R  
puts under /usr is a single  symlink into the framework.
