in reply to Overriding default libs

Are you sure threads.pm is in "/tmp/custom_module"? Or is it in a subdirectory like "/tmp/custom_module/lib"?

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

    The exact path of the .pm file is: /tmp/custom_module/lib/perl5/x86_64-linux-thread-multi/threads.pm

      Then you should use lib "/tmp/custom_module/lib/perl5";. (Perl should be able to guess the "x86_64-linux-thread-multi" bit.)

      perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
        That worked perfectly, Thanks. How deep(how many sub-directory levels) does perl look when given a path for  use lib /path/... ?
      use lib '/tmp/custom_module/lib/perl5/x86_64-linux-thread-multi/';
        No,  use lib '/tmp/custom_module/lib/perl5';
