Thank you Emmanuel, its true that in fact the default variant should be
discoverable, per your suggestion, like this for the example port of gtk2:

$ port variants gtk2

But for cyrus-sasl2, the text "*(default)*" is *missing* from the line
yielding the variant, kerberos:

$ port variants cyrus-sasl2

Should not that line read:

*kerberos (default)*

?

Thanks,

T.M.
