The above is only true if all your programs are compiled with the same
compiler. With RPM:s this isn't always the case!
Sorry, but this is the disadvantage of using dynamic loadable modules.

Can you check which file requires the above symbol:
For me:
(~) nm /usr/lib/mysql/libmysqlclient.a | grep ucmpdi2
Which should mean that this isn't a problem with the MySQL RPM !

Sorry, but I don't know how the above two RPM:s are made.

Sounds ok.

glibc 2.0.7-29 works exellent also on RH 5.2

This could still be a perl / glibc problem. If everything else is
compiled with the same compiler, except perl, it's extremely likely
that this is the source of your problems.
