in thread Can't find a module that is installed

Mea culpa, I shouldn't be making simple typos like that. Round 2:
$ cp /usr/local/lib/x86_64-linux-gnu/perl/5.22.1/forks.pm . $ perl -I. -E 'use forks' Argument "2.53_01" isn't numeric in numeric ge (>=) at forks.pm line 1 +570.

    Argument "2.53_01" isn't numeric in numeric ge (>=) at forks.pm line 1570.

    Not sure how relevant it is to your problem but that message is described in this bug report

    This is more of an issue now that the latest stable perl version is using a version of Storable which triggers this warning. From 5.22.01 perldelta:
    
           Storable has been upgraded from version 2.53 to 2.53_01.

      It appears to be very relevant. I followed the instructions in that thread for how to fix forks.pm and not the problem has moved to

      Can't locate forks/signals.pm in @INC (you may need to install the for +ks::signals module) (@INC contains: /Data/Apps/maker/bin/../perl/lib +/Data/Apps/maker/bin/../lib /Data/Apps/maker/bin/../src/inc/perl/lib +/Data/Apps/CEGMA_v2.5/lib /etc/perl /usr/local/lib/x86_64-linux-gnu/p +erl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/per +l5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/sha +re/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl- +base .) at forks.pm line 83.

      So, unless I'm misunderstanding something, the forks module needs to be updated to account for the X.Y_Z version numbers or I need to roll Storable back to a X.Y version?

    Hi,

    As a general rule copying files around is not the way to solve directories missing from @INC
