It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

Near as I can tell portage/emerge does not like something about perl.

I was actually considering unmerging perl, running the declean and revdep-rebuild, then reinstalling perl fresh. But I know that perl is kind of included in surprisingly low-level bits of the operating system and would probably brick my system.

I do not know what to do. Aside for reverting my "/" partition from the last backup, what can I do?

From assorted other threads, adding "--backtrack=300" to your emerge command will resolve this.

Wow. That seems to be working (I say seems because while my emerge no longer displays that error message, it is still compiling everything right now and could fail later on). Thank you very much.

i actually did

i unmerged perl and reinstalled to force update. that didn't completely resolve [topic=1062228]my issue[/topic], but i can confirm that gentoo is rock solid

You don't need to unmerge perl.

You could do just emerge --oneshot --nodeps perl, to upgrade it, then continue with @world. Much faster than --backtrack=10^180

Recommending installs packages with --nodeps is a very bad idea :-/

Quoting myself, how weird, huh?

The emerge ran fine. No perl problems I can see.

p.s. I've got another problem since this emerge but I'm almost certain it is not perl-related, and thus will get its own thread.

Thanks again.

Yep, that's the solution! And there's ongoing work so in future portage versions the backtrack parameter won't be necessary anymore.

For more info, head to the wiki! https://wiki.gentoo.org/wiki/Perl

Not quite.

While --backtrack=300 allows the forced upgrade to perl 5.24 to continue you still need to run perl-cleaner and even after that you will find multiple virtuals referencing old perl when attempting a --depclean. This is a really messy upgrade and it doesn't make it any better that it is impossible to hold it back.

Normally, I would agree with you.

But to this concrete case...

--backtrack means "please, hold my hand and take me into a silly and long b-tree walk, in the hope that we can find the exit, if not, then we will need to recurse using a greater depth, but there's no guarantee that you will find an exit anyway"

--oneshot --nodeps means "I know where the exit door is so please let's walk into it and be done because this is so evident that I don't want to spend 10 minutes of my life walking b-trees or whatever"

This happens on every perl upgrade. But not only, it also happens, or used to happen at least, in qt upgrades, xorg and a few others at times. You find yourself in a situation where packages block each other, and you just need to tell portage that it should just upgrade the base package and forget about silly circular blockers. After this, of course, you are the responsible to upgrade world to ensure consistency. Blockers should be gone.

In any case, --nodeps and --oneshot are parameters you can find in the same man page where --backtrack is. They are there for a reason, and you know it

I very much doubt that gentoo developers spend 10 minutes watching their screen while it resolves --backtrack=300 and then, failing that, --backtrack=1000 or whatever. It's just silly.
