Assuming you get a maximum of four hex digits in a number between dashes (otherwise the semantics of the Java version would be rather obscure too), I'd say:

sub get_bytes {
    return join '', map {
        length($_) > 2 ? pack('C', hex substr($_,0,-2)) : pack('C', he
+x $_)
    } split /-/, $_[0];
}

It splits the string on dashes, the resulting list gets mapped to characters depending on the length of the number (I leave off the last two hex digits rather than doing a logical right shift because pack returns a string) and then joined back together with no separator to yield the byte string.

Maybe someone can come up with a clever pack pattern that does it all, I'm not quite the expert there.
