Comment (by ryandesign):

 I've never looked into how this might be done so I can't give many
 pointers. Changes would probably be needed in both [source:mpbb mpbb] and
 [source:macports-infrastructure/buildbot the buildbot configuration].
 Setting up a local instance of the buildbot is a task in and of itself but
 would be a good thing to do if you plan to make improvements to the
 buildbot.

 Providing the contents of main.log is simple in that every port has one
 and it's always at a predictable location. config.log files, on the other
 hand, are an artifact of autotools build systems so not all ports have
 them and those that do might have them in different places. Some ports
 have multiple config.log files because they have multiple nested configure
 scripts; gettext is an example of that. Some use different build systems,
 like cmake or meson, that have log files of different names but that serve
 a similar purpose.
