What incantation will you use to attract the package you wish?
What signing will you do to repel the maleficent procedure?

You have to do, to write, you can not yet code by the wish.

You can look at AUTOLOAD, but this is a greedy solution.

You can pollute UNIVERSAL with your foul needs.

You poor nameless soul, sad for you, the nature, the power,
the joy, of good naming is denied. The joy of many names
lies far from you.

*truename = \&Carp::truename;

May this lead you to find one of your own true names.
That is a tag, a signing, that refers to your true being.
If not that, may it let you name those small things which
are distant and in the naming bring them nigh.

Your lib problem is the same wretchedness in another guise.
You might try to

use lib "/whereever/MyLibs/ForSome/Particular";
use Thing;
my $thing = Thing->new();
[download]

Or you might move your library. Or alias it by linking
it beside MyLibs. These are operating system actions.

Good luck. See you anon.
