This looks like a DNSSEC problem.  I don't run bind on my gentoo system,
but I did this:

$ equery -C u net-dns/bind
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for net-dns/bind-9.14.4:

which left me puzzled: the libressl flag docstring talks about a ssl
flag which doesn't exist for this package.

Try running "ldd /usr/sbin/named".  Is openssl (ie. libssl and
libcrypto) part of the output?
