How to see buildbot's results for a specific port?

[Jim DeLaHunt]

Hi, folks:

I'm starting work on my first Portfile, so expect some newbie questions 
from me for a while.

I know that we have buildbots building ports and base and other 
software, for several OS versions, with results presented at 
https://build.macports.org/ . I see Waterfall view, and Waterfall View 
Help, and a couple of grid views.

I do not see how to list just the results of building specific ports, 
"freeciv" and "freeciv-x11". The closest I can come is to see a list of 
completed builds for a builder, corresponding to an OS version, e.g. 
https://build.macports.org/builders/ports-10.13_x86_64-builder/ . But 
this list does not display the name of the ports it builds with each 
run. Nor do I see a mention of filtering by port in the Guide or in the 
Waterfall View Help page.

How do I see the build history for specific ports across a variety of 
builders?

Best regards,
