It seems that most of the live/jigsaw tests started to fail a few days
ago. See
http://bbbike.radzeit.de/~slaven/cpantestersmatrix.cgi?dist=libwww-perl;maxver=;reports=1
There are currently only FreeBSD machines with this failure listed, but
I could reproduce it on another Linux machine. Note that I always had
live tests turned on in my smokers and this was never a problem.
