[GRASS-dev] g.extension not working on debian - grass 6.4.3svn

[Paulo van Breugel]

Based on remarks from Markus, I installed r.mess (and other extensions)
from the command line rather then using the g.extension gui interface. It
does seem to do the trick

The extensions install fine, and the total manual page is now rendered when
running the extension. Meaning, including the NAME, KEYWORDS and SYNOPSIS
sections (but, a minor thing, black square instead of grass icon - i.e.,
wrong link).

Not sure if it is of relevance, but if immediately after installing this
way I run the extension from the command line, all works fine. Running it
from the command console in the GRASS GIS Layer Manager does only work
after restaring GRASS GIS though.

I didn't realize that running g.extension from the menu invoked a different
command (g.extension.py) then what used on the command line (g.extension).
It does seem to make a difference. Sorry if that caused any confusion, but
hope the above helps.

Also following a remark from Markus, I set the debug level at 3 with
g.gisenv set="DEBUG=3". I attached the output from the command line when
installing a extension.
