hello to Everybody

before all, thanks to everybody that helps me resolving my previous problem
with the "make" of postgresql: I've substituted yacc with bison and all
goes ok.

I'd like to install psql 6.3.2 on my mac LC 630 (netbsd 1.3.2).
I've installed the GNU make and bison (instead yacc) with success, but when
I do the gmake for pgSQL, at a certain point now the process stops with the
following message:
(please excuse the long one...):
