[R-SIG-Mac] upgrade to 2.6 removes 2.5?

[Julin Maloof]

Thanks Bill,

The curious thing is that installing (earlier releases) of 2.6 on other machines did not cause their 2.5 directories to be removed (and I did not delete the installation Receipts).  Maybe this behavior changed between 2.6.0 and 2.6.2?
