Hi, are you doing source ~/perl5/perlbrew/etc/bashrc at the end of your .bash_profile? You can check your config by examining your $PATH which should point to your perlbrew's bin before the system ones. Mine is like:

$ echo $PATH
/Users/1nickt/.perlbrew/libs/perl-5.26.1@dev/bin:/Users/1nickt/perl5/p
+erlbrew/bin:/Users/1nickt/perl5/perlbrew/perls/perl-5.26.1/bin:/usr/l
+ocal/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/sbin

Hope this helps!
