[GRASS-user] How to plot arrows style of speed and direction of wind...

Dear grass user

I succeeded in installing add-on, d.barb. 
The procedure of the installation is shown below (1) - (5).
I show the map drawn by the sample data.

I wish to express my gratitude to Mr. Hmish who made wonderful add-on.
Thank you !!

(1) upgrade grass
6.4.0  upgrade to 6.4.1

(2) install grass.dev

(3) installsubversion

(4) correct two make files
/usr/lib/grass64/make
Platform.make
Grass.make

---Platform.make---
# platform specific dirs
ARCH_DISTDIR    = $(GRASS_HOME)/dist.$(ARCH)
ARCH_BINDIR     = $(GRASS_HOME)/bin.$(ARCH)
ERRORLOG        = $(GRASS_HOME)/error.log

with

ARCH_DISTDIR    = $(GRASS_HOME)
ARCH_BINDIR     = $(GRASS_HOME)/bin

---Grass.make--
# GRASS dirs
GRASS_HOME          = /build/buildd/grass-6.4.0
RUN_GISBASE         = /build/buildd/grass-6.4.0/dist.i486-pc-linux-gnu

with

# GRASS dirs
GRASS_HOME          = /usr/lib/grass64
# not sure what should be here since
/usr/lib/grass64/dist.i486-pc-linux-gnu does not exist:
RUN_GISBASE         = /usr/lib/grass64

(5) install (g.exetnsion extension=d.barb) with su
