I am guessing[1] you are doing something like

perl -wc bar.pm

This attempts to synax check bar.pm by compiling it as if it were a
script, not a module. Often this makes no difference but if bar.pm is
part of a cyclical module dependancy then you'll get redefined warnings
for all the subroutines in bar.pm because bar.pm will get loaded as a
module too.

Check modules with

perl -Mbar -ce1

Or

perl -ce"use bar"

You may also want to specify -w but really each source file should
contain "use warnings".

[1] I should not have had to guess. You should have reduced your
problem to a minimal but complete test case and posted it here.
Together with the actual output you were getting.
