Folks, I was in the process of upgrading ffmpeg when I suddenly jumped out of my chair: the build was trying to pull in the bloated texlive source.
I traced that spurious dependency to libunistring. Commenting out the dependency on texlive-basic does not produce any side effect (AFAIK): the package compiles and installs fine. Since libunistring has no official maintainer, I’m going to push my Portfile version unless someone objects to it. Cheers, Vincent
