Yes, that's better than what I had in the troubleshooting section of the Rcmdr installation notes, which was sudo chmod -R a+rx /usr/local and which, as you say, would set execute permission for files as well as directories. I've fixed that now. When I first read Mark's message, I didn't realize that there were subdirectories below /usr/local that might also have incorrectly set permissions.
