If you want to add a directory to your search path (@INC), just use the
following:
use lib qw(/usr/lib/foo /usr/lib/bar);
which adds the two specified directories. As to the 'use' or 'require'
syntax, I'd recommend doing the following:
$module = "MyModule";
$tmp->import if eval "require $tmp";
This will search your @INC for the specified module (*.pm), load it, and
import any default symbols. For what you're doing, though, it sounds like
you just want to import a standard *.pl file, to which I'd recommend you just
eval the require call on that file:
unless (eval "require foo.pl") {
die "Couldn't load foo.pl!\n";
}
This will let you safely control what happens should the file not be
available, etc.
