Is it possible?
What I would like to do is be able to test either that a dependency was installed with a certain variant or that a file exists and then set a variant on the port being installed based on that information.
Background: I am reworking the gtk2 port so that it can be installed without X11. What I want to be able to do is have "sudo port install gtk2" work correctly, installing gtk2 with the correct variants for the machine its being installed on without user intervention or complaint.
I didn't try to hack a Portfile to do this, so no idea; if these are common tests, we could include them in port(1) like with the platform and architecture variants. Depending on a variant of a port to be installed will create a big mess and is imho a bad idea: If A requires C1, B requires C0 and C1 conflicts with C0 you're stuck. I'd like to avoid having this kind of conflicts in the first place by _not_ relying on variants. If it is crucial for a port to have something installed in a "non-standard" way, either create a new port that takes the non-standard options or try to make your requirements the defaults for the dependencies. A good example I just recently saw are the smlnj/smlnj-dev ports which can both be installed simultaneously (different versions); ncurses and ncursesw als come to my mind here.
