This should be harmless.

This message is generated by the curses library. It normally means
that you don't have a complete terminfo/termcap database, but there
could be other reasons.

It may be related to the GRASS binaries being incorrectly linked
against libtermlib or libtermcap. This is a known problem with 5.0.0
and 5.0.1, which will be fixed in 5.0.2.

It may be possible to fix the problem by making an appropriate symlink
in the GRASS library directory (e.g. /usr/local/grass5/lib) which
points to libncurses instead.

E.g. if the output of "ldd /usr/local/grass5/etc/set_data" contains:

	libncurses.so.4 => /usr/lib/libncurses.so.4 (0x4001c000)
	libtermcap.so.2 => /lib/libtermcap.so.2 (0x4005f000)

then making a symlink:

	ln -s /usr/lib/libncurses.so.4 /usr/local/grass5/lib/libtermcap.so.2

will make the GRASS programs use libncurses instead of libtermcap.
