Perl 5.18

Question

Hey guys, 

 

I'm stuck with a system upgrade, because of a big mess caused by Perl 5.18.

 

This is what I get:

Total: 218 packages (209 upgrades, 6 new, 2 in new slots, 1 reinstall), Size of downloads: 728,521 kB
Conflict: 1 block (1 unsatisfied)

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

dev-lang/perl:0

  (dev-lang/perl-5.16.1::gentoo, installed) pulled in by
    dev-lang/perl:0/0= required by (dev-vcs/subversion-1.8.9-r1000::gentoo, installed)

    =dev-lang/perl-5.18* required by (virtual/perl-Compress-Raw-Bzip2-2.60.0-r2::gentoo, ebuild scheduled for merge)
    (and 6 more with the same problem)

Notice the block -- that is lua, an unresolved issue from my last upgrade attempt.

 

I feel that half of my system depends on Perl 5.16 and the other half on Perl 5.18 :p. I tried to mask 5.18 but it cries everywhere, and there are packages depending on 5.16 that have no available upgrades.

 

Where should I start?

 

Thanks in advance!

I really don't understand the background or why this worked since I know nothing about perl. But I ran

# perl-cleaner --all -- --backtrack=30

which solved the problem for me. I found this solution in a Gentoo bug:

Hope it works for you, too.

Thanks work perfect :)

I just ran into this today after an emerge world update.  Does anyone know what could have caused this 3 months after the initial bug was filed?  The backtrack=30 solved the problem for me, just curious as to what would have caused this.

My last update pulled in an update to perl 5.20.1-r1 but it didn't generate any conflicts.   perl-cleaner reports all is good.
