You have installed the Perl modules in the <perl_dir> directory.
If you installed the Perl modules with the installation program, they have been stored in the <perl_dir>=<dependent_path>/runtime/perl directory.
Add <perl_dir> to the environment variable PERL5LIB:
Microsoft Windows:
set PERL5LIB=%PERL5LIB%;<perl_dir>
Unix and Linux (sh or bash):
PERL5LIB=$PERL5LIB:<perl_dir> export PERL5LIB
