I don't know how good the solution is, but if you remove the
sanity-check phase, the package builds and works.

Thanks for reporting.

The latest version of b4 no longer calls dnspython's
get_default_resolver(), so it avoids this failure.  I posted a series
for that update at https://debbugs.gnu.org/48702
(<20210527145046.11773-1-kyle <at> kyleam.com>).  It's a bit stale at this
point and has conflicts with the current master.  I'll rebase it and
send new version.

That series hasn't yet been applied, but b4 was updated in 0780164f1f
(gnu: b4: Update to 0.8.0, 2022-05-05), so I'm closing this issue.
