emerge scheduled 2 versions of the same package (dev-lang/perl-5.20 vs. perl-5.22) to build - causing conflicts

Question

I'm trying to update all my packages, so I ran:

emerge -aUDU --with-bdeps=y --verbose-conflicts @world

and I found a few package conflicts. Interestingly enough though, is that it has scheduled two different versions of the dev-lang/perl package to install:

dev-lang/perl:0

I've unmerged each of the packages that are using either versions of dev-lang/perl as a dependency (at least those that were installed and listed as causing conflicts), and I've tried masking either versions in /etc/portage/package.mask/perl by doing:

>dev-lang/perl-5.20.2

or

<=dev-lang/perl-5.22.1

But the conflicts remain.

Do I have to mask each of the packages that depend on one of the versions, or is there another way to handle this conflict?

Have you tried un-merging all those Perl "virtual" packages instead? — , Apr 24 '16 at 15:08
@Nasha, yeah, I unmerged all of those too. But they are `ebuilds scheduled for merge`. If you look in the terminal output I posted, you can see that none of the conflicting packages, or the packages causing conflicts are installed, just `scheduled for merge`. — CaptJak, Apr 24 '16 at 15:12
Have you checked out [this thread](https://forums.gentoo.org/viewtopic-t-996680-highlight-perl+upgrade+conflicts.html) on Gentoo forums? — , Apr 24 '16 at 16:56
@Nasha, geez. I wish the Gentoo forums were more like the Stack Exchange sites... Anyways, I ended up making sure that each package that wanted to pull in the older version of Perl had been unmerged, and then I explicitly masked them in `/etc/portage/package.mask/perl`. The conflicts for Perl disappeared. I'm now installing the newer version of Perl, will do `pearl-cleaner --all` and see how that goes. This might take a while to see the result because I also pulled in a dependency update for LibreOffice. Should be done updating by the time I'm 65... :P — CaptJak, Apr 24 '16 at 17:06

Using

EIX_LIMIT=0 emerge -1auvDNt -j2 --verbose-conflicts =dev-lang/perl-5.22* $(eix '-I#' virtual/perl-*)

I was able to update Perl from 5.20 to 5.22 on my system.

This is what worked for me, nothing else worked:

#!/bin/bash

# unmerge perl virtuals
emerge --unmerge $(qlist --installed virtual/perl)

# print perl blockers and quit
if emerge -pq dev-lang/perl:0 2>/dev/null | grep blocks
then
        echo
        echo "unmerge packages blocking perl upgrade"

        exit 1
else
        # upgrade perl
        perl-cleaner --reallyall -- dev-lang/perl:0
fi

exit 0
