The makefile for sysutils/xbatt

https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/sysutils/xbatt/Makefile?rev=1.32&content-type=text/x-cvsweb-markup

points to

    http://www.clave.gr.jp/~eto/xbatt/

however this site is not reachable.

As a result I am unable to review and compile the source code.
