Is it the same repo as for perl? I'm getting: root at bend ~]# perl -v This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi for perl. Since you said you're running 5.26.3 but from a standard repo which doesn't match what I'm seeing (5.16.3), I'm thinking your mismatches are due to the listed modules being built against a newer version of perl.
