Fedora Release package from rawhide converts to core 5 repository

[Dwaine Garden]

Updating with yum, and now it's pointing me back to the official fedora 
Core 5 repository.

How do I get back to updates from rawhide.   Tried to upgrade back to 
fedora-release package from development
Then tried uninstall of yum with re-install.  Nothing.  Still stuck 
pointing to official core 5 release.

Anyone else have this problem?
