Ah, cool, thanks Thomas. That helped. Starting with this hint, I
carefully compared the ncurses_cfg.h created by the devel/ncurses
port's configure script with the one in the FreeBSD base system:

http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/lib/libncurses/ncurses_cfg.h?rev=1.5&content-type=text/plain

and I found a few more configure options that I believe bring it
very close to the FreeBSD base. I think the key ones are:

--enable-termcap
--disable-database
--enable-getcap
--enable-colorfgbg
--enable-bsdpad
--disable-home-terminfo

So I ended up with:

CONFIGURE_ARGS= --datadir=${PREFIX}/share/misc --disable-overwrite \
                --enable-termcap --includedir=${PREFIX}/include/ncurses \
                --with-profile --with-shared --without-debug \
                --without-curses-h --with-termlib --program-prefix= \
                --enable-safe-sprintf --disable-root-environ \
                --with-manpage-format=gzip --srcdir=../ \
                --disable-database --enable-getcap --enable-colorfgbg \
                --enable-bsdpad --disable-home-terminfo

Would it make sense to change the port defaults to be more BSD-like?
Actually, I'm more interested in updating the FreeBSD base ncurses...

Thanks,
Matt
