Here is a generically applicable approach to handling upgrades in 
situations where a major dev-lang/perl update is queued.

1) emerge -auDN @world
2) If previous step fails: emerge -auDN --backtrack=30 @world
3) If previous step fails:
    a) emerge --deselect $(qlist -IC 'perl-core/*')
    b) Return to step #2
4) perl-cleaner -all
5) If previous step fails, follow the instructions in the error message
6) Re-select any perl modules that you may have explicitly requested

The final step won't apply to you unless you a Perl hacker.
