Can you explain what you mean? There is no "overwriting" because each R version lives in a separate directory of the framework. They never overwrite each other even if you don't use pkgutils (if you don't Apple just *removes* the old R, it doesn't overwrite anything). Please make sure you have read R for Mac OS X FAQ - in particular 12.15 should be helpful.

/Library/Receipts refers to older OS X (10.4 and earlier) and old builds of R (for those old OS).

Well, to my best knowledge that's what's in the README. If anything is unclear about that, please explain.
