lftp upgrade fails (Variant ssl conflicts with tls)

[Vincent Lefevre]

$ sudo port -v upgrade lftp
Error: Variant ssl conflicts with tls
Error: Unable to upgrade port: 1
$ port installed lftp
The following ports are currently installed:
  lftp @3.5.6_0+tls (active)

Even though ssl is the default variant, I don't think this is a correct
behavior for upgrade. I think that a default variant should no longer
be default when it conflicts with some provided variant.

BTW, is there a reason why ssl is the default variant?
