I don't think there is any way to do that, especially not if the port you
depend on already is installed without the non-default option set, since the
options used for building a port is usually not stored anywhere, so it is
normally not possible to determine if the installed port was compiled with
the necessary options set or not.


The only way I can think of to handle this situation is to create
a slave-port for the port you depend on that has the desired options set,
and then depend on this slave-port instead.
