Dear Simon,

> Did you try "Repair Disk Permissions" in "Disk Utility"?

Not previously, but I just did and some things were repaired. Then I
installed Rcmdr again (but didn't reinstall R 3.0.1), but got the same
results.

Here is the output you asked for:

> system("ls -ld /usr/local /usr/local/lib /usr/local/lib/libtcl*")
ls: /usr/local/lib/libtcl*: Permission denied
drwxr-xr-x   7 root      wheel   238 Aug 19 16:44 /usr/local
drwx------  31 macports  wheel  1054 Aug 21 16:08 /usr/local/lib

I also went back to the Disk Utility and selected "Verify Disk
Permissions". It said:

Permissions differ on "usr/sbin/pppd"; should be -r-xr-xr-x ; they are
-r-sr-xr-x .
Warning: SUID file "usr/sbin/pppd" has been modified and will not be
repaired.

This Mac is from our loaner pool and was used for one year by professor who
just retired. He did teach a technology education course so I'm not sure
what kind of things he might have played around with.

Thank you for your assistance,
Sarah
