The glibc-devel package depends on the kernel-headers package, which oddly
enough does not appear to be included in RH 7.0, and further, the
kernel-headers package conflicts with the kernel-sources package, which
*is* included with RH 7.0.
The kernel-headers package *does* exist in 7.0. I'd
check your tree to make sure it's complete.
The kernel-headers package for the 2.4 kernel is in Red Hat 7.0, but not the
kernel-headers for the 2.2.16 kernel. Sorry that I didn't clarify. It's the
latter that I'd expect to see glibc-devel depend on, considering that it's the
2.2.16 kernel that is installed by default.
Maybe the kernel header files for 2.2.16 and 2.4 are interchangeable, but pardon
my discomfort at the idea of installing kernel-header files for 2.4 on a system
based on a 2.2.16 kernel just to satisfy the dependencies of the glibc-devel
