ipv6calc @0.71.0 livecheck does not obtain the latest version

[nonstop.server@…]

Livecheck for port ipv6calc does not obtain the latest version.

% port -v livecheck ipv6calc
ipv6calc seems to have been updated (port version: 0.71.0, new version: 0.45)

According to the information on the homepage the developer does not update the page for ipv6calc at freshmeat.

Note: this tool got also its freshmeat / ipv6calc page (not maintained by the author)

Setting the livecheck URL to  ftp://ftp.deepspace6.net/pub/ds6/sources/ipv6calc/ solves this problem.
