HELP r.in.poly

Help! I'm trying to compile r.in.poly. What's wrong? I ftped r.digit and r.in.poly from moon. This is the first stuff I've had to compile in Grass and r.digit compiled OK, but r.in.poly gave the following error message.

You need to update your library as well because it is missing a new library
function.

250-plot.c:
250- replaces libes/gis/plot.c to include G_plot_line2()
250- needed by r.in.poly
250-

this library function is found under diretory

/grass/grass4.0/updates/src/libes/gis on moon

Get those library changes and compile those; then it will work.
