[CentOS] hfsplus on C7

I followed the instructions (I thought) for hfsplus on C7.
Installed elrepo
Then installed hfsplus hfsplus-tools and kmod-hfsplus kmod-hfs
rpm -qa | grep hfs clearly shows the items
kmod-hfsplus-0.0-2.el7.elrepo.x86_64
hfsplus-tools-540.1.linux3-4.el7.x86_64
kmod-hfs-0.0-2.el7.elrepo.x86_64


When I do my mount command

mount -t hfsplus  -o loop Mac.dmg   /mnt/mac
mount: unknown filesystem type hfsplus

What did I miss? Thanks,

Jerry
