 You could try using --skip-broken to work around the problem

It looks like it is trying to install glibc.i686 0:2.12-1.47.el6 because glibc.x86_64 is worth the wrong version.

yum list installed glibc

glibc.x86_64 2.12-1.132.el6 @security

How can I win this? Do not offer to reinstall, the server is not mine, everything is already spinning there.

Answer 1

glibc-devel wants to install the old one.
Updating databases via "yum update" without installing packages doesn't help?
If not, then show lists of active repositories.
