Comment (by jmroot):

 Please use `port installed` to find out what ports are installed; `port
 list` shows the versions that are available, which are not necessarily the
 ones currently installed.

 Your tk is installed with +x11. If you would prefer a native UI, use tk
 +quartz. Otherwise, you need an X11 server, either the xorg-server port or
 the package from [https://www.xquartz.org/ xquartz.org]. It looks like
 that's what you're missing.
