</span>If you are using GRASS 6: the script has been written for GRASS 7. You<br>
can install both 6 and 7 in parallel on the same computer. However, I<br>
see a link to a GRASS 6 version of the script in the Wiki page.<br>
<br>
If you are using GRASS 7: The reason is that it has not been<br>
implemented as Python script but as Shell script. To my knowledge<br>
g.extention (the extension manager) is not capable to deal with shell<br>
scripts.<br>

<br>
</span>You can simply download the script from here:<br>
<a href="http://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.forestfrag/r.forestfrag?format=txt" target="_blank">http://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.forestfrag/r.forestfrag?format=txt</a><br>
and put it into the search path in your GRASS session. Be sure to set<br>
the "executable" flag.<br>
<br>
Please let us know how it goes.<br>
