Plugin won't work, throws error in the console when loading

[NSGauge]

After installing the plugin I was unable to enable it in the Configure/Plugins menu, as it didn't show up there. After running Plover (debug) I discovered the following error in the console:

I haven't used this plugin myself for a long time... but anyway it appears to be fixed now.
