Comment (by ryandesign):

 Replying to [comment:6 ryandesign]:
 > The rebuild will work, but the dependencies will not be correctly
 recorded. A user will then be able to uninstall libgcc6, without MacPorts
 complaining, which will break octave.

 And since the buildbot deactivates all ports between builds, and because
 octave wants to run octave-cli in its post-activate block, all ports that
 depend on octave will fail on the buildbot, because octave will fail to
 activate:
