That explanation in https://dev.gnupg.org/T3027#95879 sounds very
accurate based on what I have seen. I'll give the patch a shot!

The dependency chain for nettle is via gnutls, though I admit to not
attempting to identify what dependency that might be. As far as glib,
I am not sure why I thought that may be involved somehow ... maybe a
socket routine or something. I apologize for incompleteness here, I
have been time limited in debugging this issue as thoroughly as I
would like to.

Thanks!
