No, that's not right. The tree is consistent and portage can figure out
how to get from perl-5.24 to perl-5.26

You probably have a difference locally, I would search through
/etc/portage looking for entries that mask some perl modules and peg
them to 5.24 versions.

Failing that, maybe you have a package installed that depends on a 5.24
version of some module and this is the ripple effect

Perhaps run emerge with "--verbose-conflicts" and also "emerge -e world"
and post the results
