The only thing that --enforce-variants changes is that MacPorts will rebuild a
port that is not considered outdated. From port(1):
Note that in selecting the variants to use in the upgraded build of the
port, any variants specified on the command line take highest precedence,
then the variants active in the latest installed version of the port, and
finally the global variants specified in variants.conf, if any. Note that
upgrade will not normally rebuild a port only to change the selected vari-
ants; you can either specify --enforce-variants, or deactivate the port
and reinstall it with different variants.
