	No it doesn't include it (anymore?) maybe that changed with some
tool update. Or maybe I forgot. Mine failed the same way this time (I
build it more than a year ago).

Simply add the line (at about line #464):

LIBS += -lpthread

after the zib library is added:

LIBS += -lz

and before the all target:

all:

	Now it links fine and is the same as my original.
