Created attachment 222024 [details] local patch for an interim fix. As reported in comment to bug #252742, wsdd 0.6.3 has a bug that it does not work on FreeBSD. https://github.com/christgau/wsdd/issues/80 While waiting for a fix, as suggested in the issue, add local patch for an interim fix.
A new version that address this problem has been released. I will remake the patch and re-issue.
