Comment (by kencu):

 I saw something like this too, when I was updating one of my systems ...
 there is something to be tweaked in the way MacPorts' calculates
 dependencies, you're right. I found it easy enough to fix -- just update
 llvm-8.0 (in your case) first, and then you should be good to go again.

 }}}

 so :
 {{{
 sudo port -v upgrade llvm-8.0
 }}}
 and when that is done, DON'T allow rev-upgrade to rebuild anything broken.

 Then go ahead with
 {{{
 sudo port -v upgrade outdated
 }}}
