Description

MacOS 14.2.1 (23C71). Installed macports for scratch. (clean uninstall, reinstall)

Running port install graphviz fails with the following:

$ sudo port install graphviz
--->  Computing dependencies for graphviz
The following dependencies will be installed:
 cabal
 dvipng
 gd2
 ghc
 libavif
 pandoc
 texlive
 texlive-bin-extra
Continue? [Y/n]:
Error: The following dependencies were not installed because all of them have unmet dependencies (likely due to a dependency cycle): gd2 libavif pandoc cabal ghc texlive texlive-bin-extra dvipng
Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.

Summary: graphviz @ 2.9.1 installation fails: "unmet dependencies (likely due to a dependency cycle)"dependency cycle involving ghc, texlive, gd2

ghc -> texlive -> texlive-bin-extra -> dvipng -> gd2 -> libavif -> pandoc -> ghc

Port: dvipng gd2 ghc libavif pandoc texlive texlive-bin-extra added; graphviz removed

You could probably fix the dependency cycle by removing ghc's dependency on the texlive metaport and adding whichever specific texlive ports it actually needs, assuming that doesn't include texlive-bin-extra (I haven't checked). This is probably a good idea anyway (will it work if the texlive installed is the +minimal variant?)

Either way, though, it still seems not great that installing gd2/libavif requires pulling in such heavyweight dependencies...

The heavy ghc dependency comes from pandoc. libavif only needs pandoc to build the documentation which is in the docs variant which is on by default on recent macOS versions. A solution could be to disable the docs variant by default or better yet move the documentation to a separate libavif-docs subport.

Thank you. How do I do that?

ghc’s user manual is built using hadrian docs, which itself uses sphinx/xelatex/latex:

Therefore, it should work to replace ghc’s dependency on texlive with texlive-xetex. And this will eliminate the dependency on texlive-bin-extra:

port echo rdepof:texlive-xetex | grep texlive-bin-extra

Definitely test beforehand with the CI within a PR, though.
