amd64 did not have:

devel/py-pytest-twisted
devel/py-twisted
net/py-dpkt
security/nist-kat
security/openvpn

installed and so was not doing the same sequence of dlopen
calls.

After adding those, the amd64 run fails like aarch64: It then starts to try
to use .../cryptography/hazmat/bindings/_rust.abi3.so leads to the problem.

This appears to be tied to devel/py-twisted and/or devel/py-pytest-twisted
but like anything leading to loading
.../cryptography/hazmat/bindings/_rust.abi3.so is going to get the
problem.
