Hi Alex,

good work :) I guess you've already fixed your own repo, but I'll open
a pull request anyway.

If you want to try "my" patched version (its really not mine, I just
ported the patch to socket_pdu),

git pull https://github.com/marcusmueller/gnuradio.git
socket_pdu_fix_resolver_issue

Greetings,
Marcus
