I am trying to install the glibc-headers package on a fresh install of the 7.5 beta 1 build, but I keep ending up with a dependency error. Yum tries to resolve it into installing the 32-bit glibc (which I do not want), and fails. Following the advice and changing the Yum configuration does not help.

LC_ALL=C yum install glibc-headers

yum can be configured to try to resolve such errors by temporarily enabling
disabled repos and searching for missing dependencies.
