Did you look on http://backpan.cpan.org, the official CPAN archive?

xmaths author directory, http://backpan.cpan.org/authors/id/X/XM/XMATH/, seems to contain the old versions. xmath i also here from time to time, so you might want to contact him directly. I believe that the prerequisite of 5.8.1 was because of some bugs in 5.8.0, but you'll find that out soon enough ...
