Thanks, you have clarified it and I'm keeping a copy in my folder of stuff I 
send people when they ask me questions I've eventually answered.

But the package I really want to use is still looking for the .i586 version, and 
the other stuff I have will use that, and performance is not an issue compared 
to network and display slowness.

I did try erasing glibc.i686 and installing glibc.i586, that got all of the 
programs but one going. One is still whining, I just haven't had time to chase 
it yet, but I think that the two of you have defined the issues well enough to 
get me to a solution eventually when I bang on it one more time. I suspect that 
removing more i686 and dropping to i586 will do the job.

Thanks to both of you, and the other folks who offered suggestions, I appreciate 
the thought.
