[GRASS-user] g.extension copile failure

[Alexandre Villers]

Good evening,

I'm trying to install add-ons on GRASS 6.4.1 running on a Ubuntu 10.04 - 
64 bits version with g.extension. I get this error message

/Fletching <i.landsat.acca> from GRASS-Addons SVN (be patient)...

I found a bug report <http://trac.osgeo.org/grass/ticket/1180> through a 
message from Markus Neteler but I must confess that I did not really get 
what was the solution ?

Thanks for any hint

P.S.: I guess it could be nice that some important points are included 
explicitly in the help file of g.extension, such as "to use g.extension, 
you need to install subversion as well as GRASS dev packages (on 
Linux)". I know it is certainly obvious for people playing with GRASS 
everyday but it could be useful for beginners and avoid the step "I run 
the command, get an error message, try to understand why and fix it, 
rerun the command, get another error message..." It is also highly 
probable that I missed a key sentence/paragraph in a document I should 
have read more carefully.
