mail/p5-Mail-DKIM fails with spamassassin

I just updated a system to Q3 and noticed that welcomelist_dkim was not
working, and it seems to be because of:

Oct 22 10:37:07.056 [18709] dbg: dkim: cannot load Mail::DKIM module, DKIM checks disabled: Can't locate Crypt/PK/Ed25519.pm in @INC (you may need to install the Crypt::PK::Ed25519 module) (@INC entries checked: /usr/pkg/lib/perl5/vendor_perl/5.38.0/x86_64-netbsd-thread-multi /usr/pkg/lib/perl5/vendor_perl/5.38.0 /usr/pkg/lib/perl5/site_perl/5.38.0/x86_64-netbsd-thread-multi /usr/pkg/lib/perl5/site_perl/5.38.0 /usr/pkg/lib/perl5/5.38.0/x86_64-netbsd-thread-multi /usr/pkg/lib/perl5/5.38.0) at /usr/pkg/lib/perl5/vendor_perl/5.38.0/Mail/DKIM/PublicKey.pm line 18.

I see that p5-Mail-DKIM was recently updated, but that
p5-Crypt-PK-Ed25519 does not seem to exist in pkgsrc and p5-Mail-DKIM
does not seem to depend on it.  Thus it seems all uses of p5-Mail-DKIM
will fail.

Running 'make test' in p5-Mail-DKIM, I get
  Failed 14/19 test programs. 0/36 subtests failed.
with a lot of
  Can't locate Crypt/PK/Ed25519.pm in @INC (you may need to install the Crypt::PK::Ed25519 module)

So it seems like we just need to package that and depend on it.

Am I understanding the situation correctly?
