At the moment there's not much you can do about it, except the method outlines
below. The problem is that saved and unsaved scripts get executed in different
ways: Saved scripts get executed as files, unsaved as "Pseudofiles" in memory.
Until 5.0.7, MacPerl would before executing change the current directory to
the directory the script was in, but would omit that step for pseudofiles.
In 5.1.0, the directory is set even for pseudofiles, provided the window was
saved at least once.

You can either add search paths in the Preferences... dialog or save your file
in the "lib" folder.
