pete 248 /\ port deps auctex +emacs_app
Full Name: auctex @12.3_0+emacs_app
Build Dependencies:   texlive-latex, texlive-bin-extra
Library Dependencies: emacs, emacs-app
Runtime Dependencies: texlive

[jjstickel (Jonathan Stickel)]

It looks like perl is brought in via recursive dependencies of texlive-latex. In fact, it flags both perl5.28 and perl5.30:

$ port rdeps auctex +emacs_app
The following ports are dependencies of auctex @12.3_0+emacs_app:
  texlive-latex
    ...
    texlive-basic
      texlive-common
      texlive-bin
        perl5
          perl5.28
        ...
                        perl5.30

But I'm not about to try to sort that out. Anyway, I think this ticket should be closed.

Yes, you're right! I forgot to copy my patched versions of some Portfiles over the rsynched version. Some of these are from the past, some want to use already Python 3.9…

After correcting this issue a new problem appears: Error: Can't install emacs-app because conflicting ports are active: emacs-app-devel.

This is a separate issue from auctex and not a bug.
