Always happens to us techie types, the speaking too soon that is.

Did you try doing ldd for links to see what it was saying it was missing?

I have never used ldconfig (at least, not manually, don't know about 
programs that do it during install scripts). I know it's supposed to 
create the needed sym links to libraries on systems, but never tried it 
myself manually. Everyone I've ever heard of using it though has had the 
mixed library problems (or perhaps the problems already existed and 
lconfig only made them more obvious).

I've had the unluck of having to shut my system down with case switch when 
I had a HD go bad on me and start spewing errors.

Always back-up before making critical changes... yep, rule 0 when mucking 
around with computer software.

This is very possible, try ldd on links (you'll have to execute this on 
the actual program I think as opposed to doing it on the symlinks to it). 
See if it tells you anything else. It might be an issue of needing some 
other library not currently installed.

I would hope not. But, as I mentioned above, I've never run ldconfig 
manually, and mayhaps when it's run inside the install scripts, they use 
command line switches and such to prevent any type of foul ups.

Easy enough to get back to it working at least since you have the backup 
to restore from. Then, after re-installing glibcso, see what else is 
needed for links graphical.

Also, was links graphic working prior to the glibcso upgrade to SW91? If 
so, it might very well be something that was changed with the new version 
of glibcso instead of a problem with links graphical (there are very 
minute tiems when the libs may not be 100% backwards compatible, I've just 
never experienced it myself).
