What does this error mean and how can it be fixed?

It means that, when perl-5.38.2 loads the B module (B.pm), instead of loading the correct version (1.88) of B.pm, it's loading a B.pm (version 1.68) from an older perl installation.
You need to modify perl-5.38.2's @INC so that version 1.88 of B.pm is located and loaded *before* this old version of B.pm is located and loaded.

If you require more assistance with this, it would help if you could provide the output of running: 
perl -le 'print $]; print for @INC;'
