Oh, and the i586 and i686 can't be in at the same time.
Glibc is a relatively special case, where the compiler optimizations
used to compile it can actually have a significant effect across the
system, even if the other items are not compiled with the same set of
optimizations.
So, to sum it up simply:
On 32-bit x86
===
Pick One:
* i586 (good)
* i686 (better, but only if your hardware supports i686)
On 64-bit x86_64
===
Pick one:
* x86_64 (only option)
On a Multilib system (32bit and 64bit libs installed side by side)
===
* Pick One from the 32-bit x86 list (i586 or i686)
* Pick One from the 64-bit x86_64 list (x86_64)
This gets even more complicated on sparc, be glad you're on x86! :)
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.
