# These exact steps haven't been tested, as I ran them in a different order when manually installing.

# Install dependencies
yum -y install gcc make patch  dkms qt libgomp
yum -y install kernel-headers kernel-devel fontforge binutils glibc-headers glibc-devel

# Install VirtualBox
cd /etc/yum.repos.d
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo
