turle has existed and required tkinter to work pretty much forever. Some potential courses of action, or variations thereof:

 - Unconditionally depend on x11-toolkits/py-tkinter *and* anything else installed by the stdlib that depends on external libraries (like sqlite doesn't work without databases/py-sqlite3), because turtle is not a unique case.

 - Add OPTIONS for all external library dependencies (this is technically an incomplete solution if it doesn't also remove modules when the options are disabled)

 - Don't install any module which has a third party dependency in lang/python* ports, and install/package them with the respective sub-packaged port

 - WONTFIX (asking if the error message is enough for users to grok what to do)

 - Stop sub-packaging

 - ...

IMO (3) is what should be done: turtle should be a separate port.

I haven't thought much about the implications between the options yet, but if we do go that route, we should do it with, and for, other modules that require external dependencies or that don't work unless other sub-ports/packages are installed. At this stage there's no additional or different impact for turtle than with other modules with the same issue (sqlite3, etc)

I agree.

Awesome. Let's leave this here as a medium-term reminder. We (python + interested parties) should think critically about the implications of the options (or others), and come up with a reasoned decision.
