I would and try to install as many dependencies via pkg_add as you can
first. Looking at the list of deps, I think at least these would be
worth doing -
py3-yaml
py3-dnspython
py3-urllib3
py3-requests-oauthlib
py3-idna
py3-cryptography
Then create a venv, set to use system packages where possible and
try installing:
$ python3 -m venv --system-site-packages octodns
$ cd octodns
$ bin/pip install octodns
$ bin/pip install octodns-azure
If that isn't enough, look at what it's trying to install when it fails
and see if that's available as a system package (pkglocate can help
if you're not sure of the package name - try "pkglocate $modulename |
grep ^py3-") and if so, pkg_add it and try again with pip.
If this still doesn't help, your best option is probably to update to
a snapshot (which at this point is *very* close to what will be 7.4)
where cryptography 41 is available in packages - though when I tried
on a recent snapshot it didn't list anything which actually wanted 41.x
as the only version restrictions on cryptography where >=2.5.
