Take a look at perl lost its modules!, and specifically the reply Re: perl lost its modules!.

cpan Manip.pm

You want:

cpan Date::Manip

or better if you have cpanm:

cpanm Date::Manip

Re^2: Issue with @INC

    That was indeed my first stop. However I'm not making the connection. I've got no PERL5LIB.

    [SiDMBP2:~] urinine% echo $PERL5LIB PERL5LIB: Undefined variable.

    I'm just not sure where the @INC gets set, and the examples on that site such as:

    $ PERL5LIB=/tmp/foo perl -M-lib=/tmp/foo -le 'print for @INC'

    will remove the offender temporarily, but 5 seconds later a print of @INC shows its back.

    I appreciate your help. Thanks.

      I've not used MacOS since it was called OS X, this is perhaps out of date, my gut says it probably is. For your perl related problem I'd suggest leaving the system perl alone, install your own perl elsewhere on the system. perlbrew or just INSTALL giving it a prefix.
