This ensure we also check for other packages which are used instead
of the requested one, which does not work with rpm -q:
[root@brett ~]# rpm -q vim
package vim is not installed
[root@brett ~]# yum --assumeyes --quiet install "vim"
Package 2:vim-enhanced-7.3.056-1.fc14.x86_64 already installed and
latest version
[root@brett ~]# rpm -q --whatprovides vim
vim-enhanced-7.3.056-1.fc14.x86_64
