Net::Z3950::Simpleserver 1.14+ requires yaz 4.2.x, as well as currently
suffering from a Makefile.PL problem that involves a hard-coded path to
yaz-config (https://rt.cpan.org/Public/Bug/Display.html?id=70444).
Provide a sed command to resolve the latter problem and upgrade our
"current version of yaz" to yaz 4.2.x.
