So responding to a query from a colleague I just tried g.extension in GRASS 7 that I compiled a few hours ago. Note that I'm running this from the terminal and yes GRASS_ADDON_PATH is set properly.
<div><br>
</div>
<div>
<div>$GRASS_ADDON_PATH</div>
<div>bash: :/Library/GRASS/7.0/Modules/bin</div>
<div><br>
</div>
<div>I start running g.extensions with just the normal default settings</div>
<div><br>
</div>
<div>
<div>g.extension extension=r.stream.order</div>
<div>Fetching <r.stream.order> from GRASS-Addons SVN (be patient)...</div>
<div>Compiling...</div>
<div>mkdir: /Applications/GRASS/bin: Permission denied</div>
<div>make: *** [/Applications/GRASS/bin] Error 1</div>
<div>ERROR: Compilation failed, sorry. Please check above error messages.</div>
<div><br>
</div>
<div>First of all, this is wrong. Instead of putting this into the default, GRASS_ADDON_PATH, it is trying to create a new bin directory inside the GRASS app.</div>
<div><br>
</div>
<div>GRASS 7.0.svn (nc_spm_08):~ > sudo g.extension extension=r.stream.order</div>
<div>dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid</div>
<div>You must be in GRASS GIS to run this program.</div>
<div><br>
</div>
<div>Now it won't let me use sudo to run g.extension. </div>
<div><br>
</div>
<div>So I try to force g.extension to use the proper directory specified by GRASS_ADDON_PATH</div>
<div><br>
</div>
<div>
<div>
<div>GRASS 7.0.svn (nc_spm_08):~ > g.extension extension=r.stream.order prefix=/Library/GRASS/7.0/Modules/bin</div>
<div>ERROR: Unable to create '/Library/GRASS/7.0/Modules/bin/bin': [Errno 13]</div>
<div> Permission denied: '/Library/GRASS/7.0/Modules/bin/bin'</div>
</div>
</div>
<div><br>
</div>
<div>Again permission denied.</div>
<div><br>
</div>
<div>
<div>sudo g.extension extension=r.stream.order prefix=/Library/GRASS/7.0/Modules/bin</div>
<div>dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid</div>
<div>You must be in GRASS GIS to run this program.</div>
<div><br>
</div>
<div>And again, I get a bogus message when I use sudo to override the permissions issue.</div>
<div><br>
</div>
<div>So there is no way this can work AFAICT. Maybe it work in GRASS 6.</div>
