how to tell what options sendmail pkg was built with?

I'm in sendmail hell again.  Trying to fix broken sendmail because
libssl.so.11 disappeared, so my sendmail from ports died.

I originally built it from ports to try to shut up this error from stock
sendmail:

Warning: Option: AuthMechanisms requires SASL support (-DSASL)
Warning: Option: AuthOptions requires SASL support (-DSASL)

It would be nice if one didn't have to go through the ports pageant
just to get a working sendmail.

There's a sendmail pkg.  How does one determine what options that
was built with, short of installing it and trying it?  Is that documented
anywhere?  The pkg command doesn't seem to have a way to query
for that information.

Lots of googling has failed to turn up an answer.

Thanks,
Bill Dudley
