openvpn

[nightowl]

Is it possible to have vpn set up in gnome on a guixsd installation?  I 
am trying this and having some trouble.

I have added the openvpn and network-manager-openvpn packages to my 
config.scm file.

I also set the services as follows:

  (services (cons* (gnome-desktop-service)
                   (modify-services %desktop-services
                      (upower-service-type config =>
                        (upower-configuration
                          (inherit config)
                          (use-percentage-for-policy? #t)
                          (percentage-low 30)
                          (percentage-critical 27)
                          (percentage-action 25)
                          (critical-power-action 'hybrid-sleep)))
                      (network-manager-service-type config =>
                        (network-manager-configuration
                          (inherit config)
                          (vpn-plugins network-manager-openvpn)))
                      (udev-service-type config =>
                        (udev-configuration
                          (inherit config)
                          (rules (cons* android-udev-rules
                                        (udev-configuration-rules 
config))))))))

when I reconfigure with this, I get a failure to build with the 
following log file:
