[R-SIG-Mac] Permissions still not quite right

[Jussi Piitulainen]

The 2.0.1 installer is much better about permissions than versions
before 2.0, but it still changed the owner of /Applications:

User differs on ./Applications, should be 0, owner is 502
Owner and group corrected on ./Applications
Permissions corrected on ./Applications

It really should leave the owners and permissions of existing
directories alone.

I'm on 10.3.6, so I installed the version for 10.3+.
