Cannot find package "encoding"….

[trident60]

Hello,
When I try to "make" I get the following error and not sure how to proceed (I'm not a developer - at all…lol). I do not have an "encoding" folder anywhere.
Thanks for any help!

encoding is the standard lib in go, do you set GOROOT correctly? e.g, export GOROOT=/usr/local/go or other?
