You can run the thing with
which avoids issues in #! paths (no guarantee they will
have Perl in the same place you do.
At that point you can create a local directory with:
directories in it. Put anything you need to take with
you -- including your own modules -- under ./lib. At
that point you can start your code with:
use FindBin qw( $Bin );
use lib "$Bin/../lib';
to include the local library directory:
/path/to/perl ./bin/frobnicate 'whatever';
will set $Bin to "/blah/blah/bin" and leave you
using "/blah/blah/bin/../lib" for your modules.
Anything you need to take with you can be in
the lib directory.
Add the same thing to your ./t files and you can
sanity check the thing with "prove" before trying
to run the remaining code.
