 Hi,

 currently the build logs are highly cluttered with warning messages such
 as:

 {{{
 Make/Grass.make:423: warning: overriding commands for target ...
 Make/Grass.make:414: warning: ignoring old commands for target ...
 Make/Script.make:47: warning: overriding commands for target `install'
 Make/Rules.make:99: warning: ignoring old commands for target `install'
 }}}


 e.g. using the 6.4.3svn wxGUI g.extension.py to install an addon shell
 script creates this output in the GUI output window:
 {{{

 but if you "grep -v 'warning: .* commands for target'" away the useless
 warnings that gets reduced to this:

 {{{
 Fetching <r3.in.xyz> from GRASS-Addons SVN (be patient)...
 Compiling...
 /bin/sh: cannot create
 /home/hamish/dev/grass/svn/grass64svn/dist.i486-pc-linux-

 nonexistent
 sed: couldn't flush stdout: Broken pipe
 Installing...
 Updating metadata file...
 Installation of <r3.in.xyz> successfully finished
 }}}

 ... much more informative and you have a much better chance to spot any
 real errors which may have happened along the way.

  * what does it mean?
  * if it is benign, can we make it go away without masking any real
 problems?


 thanks,
 Hamish
