LibreCMC Wireguard Issue

[xx xxx]

I have a Thinkpenguin TPE R1100 Router with a Librecmc snapshot dated 13 Nov 2017 installed.
I've run "opkg update" and then unsuccessfully tried to install Wireguard [Luci-proto-wireguard} via both the cli and wui. In both cases I get the following errors:
root at libreCMC:~# opkg install luci-proto-wireguard
Installing luci-proto-wireguard (git-17.290.15350-38115e8-1) to root...

Collected errors:

* opkg_install_cmd: Cannot install package luci-proto-wireguard.

Any ideas how to resolve?
