build fails, instructions not enough...

[bkerin]

probably just that I know zip about go but after I followed the instructions I get:

$ go build ./
main.go:15:2: cannot find package "github.com/hanwen/go-fuse/v2/fs" in any of:
/usr/lib/go/src/pkg/github.com/hanwen/go-fuse/v2/fs (from $GOROOT)
($GOPATH not set)
main.go:16:2: cannot find package "github.com/hanwen/go-fuse/v2/fuse" in any of:
/usr/lib/go/src/pkg/github.com/hanwen/go-fuse/v2/fuse (from $GOROOT)
($GOPATH not set)
main.go:17:2: cannot find package "github.com/hanwen/go-mtpfs/fs" in any of:
/usr/lib/go/src/pkg/github.com/hanwen/go-mtpfs/fs (from $GOROOT)
($GOPATH not set)
main.go:18:2: cannot find package "github.com/hanwen/go-mtpfs/mtp" in any of:
/usr/lib/go/src/pkg/github.com/hanwen/go-mtpfs/mtp (from $GOROOT)
($GOPATH not set)

So looks like it doesn't fetch dependencies automagically. I took a brief try at go-fuse but it doesn't seem to hav installation instructions and I don't know what to do
