I git cloned DateTime module from cpan. I already had a DateTime installed. I added a new method in DateTime.pm and worte a test for a new method added. Now when I run the script it uses the already installed DateTime module and not the one I have modified and get error "undefined sub new_subname".
I tried setting PERL5LIB and use lib pragma so that the test script finds modifed cloned DateTime.pm but din't help.
I would like to know how Perl gurus/monks solve this issue and contribute to CPAN Module.
