Installing tkinter on FreeBSD

[Dick Holmes]

I am trying to use tkinter on a FreeBSD system but the installed 
versions of Python (2.7 and 3.6) don't have thinter configured. I tried 
to download the source (no binaries available for FreeBSD) and build a 
new version of Python but the build reported that it couldn't install 
_tkinter. Despite this report, Python works for non-tkinter 
applications. Is there a magical formula for configuring tkinter during 
or after a build??

TIA!
