use FindBin qw( $RealBin );

use lib "$RealBin/../lib";

is basically equivalent to 
use Cwd            qw( abs_path );
use File::Basename qw( dirname );

use lib dirname(abs_path($0)) . "/../lib";

[download]

(I don't know if the latter works on VMS.)

Note that you should always use $RealBin. Using $Bin will cause your program to break if it's run via a symlink.
