On file main.go and config/config.go, the gcfg package needs to be updated to match the correct address, since code.google.com is no longer available.
config/config.go:10:2: cannot find package "code.google.com/p/gcfg" in any of:
/usr/lib/go-1.6/src/code.google.com/p/gcfg (from $GOROOT)
/src/code.google.com/p/gcfg (from $GOPATH)
main.go:12:2: cannot find package "gopkg.in/p/gcfg" in any of:
/usr/lib/go-1.6/src/gopkg.in/p/gcfg (from $GOROOT)
/src/gopkg.in/p/gcfg (from $GOPATH)
To get it to work I needed to update both files from "code.google.com/p/gcfg" to gopkg.in/gcfg.v1 after that the build command worked as expected and the binary was generated.
