netpipes @4.2 fails to perform a livecheck

[nonstop.server@…]

Port netpipes fails to perform a livecheck.

% port -v livecheck netpipes                                      
Error: cannot check if netpipes was updated (regex didn't match)

Setting variables livecheck.regex, livecheck.type, and livecheck.url solves the error.

% port -d livecheck netpipes

netpipes seems to be up to date
