I'm running 
NetBSD other.reilly.home 1.6ZK NetBSD 1.6ZK (OTHER) #0: Sat Feb 28 18:34:02 EST 2004  root@other.reilly.home:/home/obj/sys/arch/i386/compile/OTHER i386

As far as I could tell, the BUILDING process at that
date went fine, but ever since I've been unable to get
past the config of groff when I "./build.sh tools".  The
tools/groff/obj/build/config.log file says:

configure:2389: result: no
configure:2390: error: a working C++ compiler is required

So it looks as though I haven't compiled one of the C++
libraries properly, or something.

Can someone give me a hint as to how I can bootstrap myself back
to having a working build environment?  My /usr/src tree has
been cvs updated this morning.

Thanks,
