With the use of go modules, the btcdPkgPath will no longer be `github.com/btcsuite/btcd`, but end with a version string (e.g. btcd@v0.0.0-20181129140220-beb77e89572a). This trips up build.ImportDir, which will return a ImportPath of ".", since this package cannot be found in the go path. There are probably several ways of fixing this, by clever string magic, but seems easiest to just hardcode the btcd package name.
