I do the same thing in certain scripts, so would be curious if someone suggested another solution.

Also, I use __FILE__ instead, to ensure that it's relative to the current file instead of the executing script.

# use lib <Relative Directory>
use lib;
use Cwd qw(abs_path);
use File::Basename qw(dirname);
BEGIN {
    my $dirname = dirname(__FILE__);
    my $perl = abs_path("$dirname/../../perl");

    lib->import($perl);
}
