Thanks, Tom, for your speedy reply.

As far as Onyx is concerned, the homepage is flogging MacKeeper (ugh). Is Onyx MacKeeper in disguise?
I have a supplemental question: As I mentioned in my first post, this happened after a 'fresh 10.7.5 install.' What does that mean? Has the original system been replaced, or just repaired? What would happen, if I were to start up from an external HD, delete the system, and then do a fresh install? Or does 10.7 look for 10.6 to proceed?
I am hornswoggled!
After I ran the Terminal commands, and got the No such file or directory, I gave up, closed the computer, and had a cup of coffee.
After I re-opened it, I checked the Language & Text settings one more time, and, voilà, everything was there...
So the sudo commands must have worked...
