I'm not sure if it's still an issue but FreeBSD has removed bison
from the base system (I think NetBSD has as well but it was a long
time ago) the problem is that last I checked FreeBSD's yacc can't
handle one of postgresql's grammar description files and therefore
requires bison to be present.

Basically the configure script ought to abort if bison isn't found,
yacc doesn't work as a replacement.
