On earlier this year, NetBSD have introduced terminfo in its development
tree and termcap library is replaced with small library to provide
minimum compatibility. Specially, tgetent() is changed not to store
termcap entry in the supplied buffer. Since emacs termcap code expects
actual entry filled, emacs doesn't work anymore on such system (strlen
call on the buffer returns meaningless value).
I guess it is better to configure emacs to use terminfo instead on
NetBSD which has terminfo.
Here is a changes to configure.in to check availability of terminfo:

Thank you. We can certainly install this on the trunk, but I wonder if
it (or the equivalent) should go in the emacs-23 branch?

Yes, I think so.

I've installed it in the trunk. emacs-23 will need a different patch,
since there terminfo is not set by configure, but hard-coded in
src/s/netbsd.h. I don't know how to write that patch (some check of
the netbsd version number? Blech.)

The terminfo library is commited to netbsd trunk on 2010 feb. 03 and
that is between netbsd 5.99.24 (2010 jan 19) and 5.99.25 (2010 mar
29). The version symbol __NetBSD_Version__ is defined in sys/param.h
like this:
#define __NetBSD_Version__ 599002600 /* NetBSD 5.99.26 */
but the header file isn't handy as FreeBSD's osreldate.h (it includes
some other header files and not suitable to create Makefile.)
Instead, I've found that we can use HAVE_TERM_H. /usr/include/term.h
is is header file for terminfo.
I built emacs-23.2 on following two systems with applied patch below.
The former has terminfo but the latter doesn't.
