ah - /usr/ports/UPDATING  -- thank you

Don't know that I have gone past /usr/src/UPDATING, silly me :(

    For ports users wanting to keep version 3.6 as default,
    add DEFAULT_VERSIONS+= python=3.6 python3=3.6 to make.conf

and (maybe)

      AFFECTS: users of Qt 5 in presence of binutils
              :
     ...lib/libQt5Core.so:(.dynamic+0x27ac8): multiple definition of `__bss_start at Qt_5'
     ...lib/libQt5Core.so:(.dynamic+0x27ac8): first defined here
     ...lib/libQt5Core.so:(.dynamic+0x27ac8): multiple definition of `_edata at Qt_5'
     ...lib/libQt5Core.so:(.dynamic+0x27ac8): first defined here
     ...lib/libQt5Core.so:(.dynamic+0x2b2d0): multiple definition of `_end at Qt_5'

So python for sure - thanks again. With some of the sub-sub version stuff can 
the port/package makers not cover this with the way the Makefile-s define 
requirements? Qt is a pretty basic component. It just went 4-->5 I do not 
remember having this issue during the "4" days.

Sad to say if I knew about /usr/ports/UPDATING I forgot. Call it a senior 
moment. Thanks guys

Doug
