See if your fedora-rawhide repo is enabled. Edit the file /etc/yum.repos.d/fedora-rawhide.repo. Find the first line that reads enabled= and make sure it reads enabled=0. Alternatively, using the yumex interface, click on the repository icon and disable rawhide there. Then try installing packages.
Edit: you do not want to be installing Fedora 10 packages in Fedora 9.
