A currently unstable CI?

[Xim]

Dear developers,

About an hour ago I submitted a modified commit which only contains a typo fix in the note.

To my surprise, Travis Build failed for two times, both reported that one of my dependencies failed.
I checked the two logs. 
https://travis-ci.org/macports/macports-ports/builds/670449019 
and
https://travis-ci.org/macports/macports-ports/builds/670450648

Both of them failed with dependency affairs. The difference is where the build fails.
My Portfile does not explicitly specify any extra dependencies so I suspect the stability of the builder.

Any actions may I take?

Regards,
Xim
