[GRASS-user] Installing addon's using g.extension on Mac OSX 10.7.5?

[William Kyngesburye]

g.extension should work.  The main key is that you need to install the Xcode command line tools.  This can be done either from the Xcode app (free from app store), or by downloading the command line tools installer separately (from an Apple developer account).

The old "modbuild" thing could still work but g.extension is better.  The readme mentioned is probably the modbuild readme, which doesn't help you with g.extension.

I've tried every way I can think of to run g.extension both through the qGIS GRASS command as well as in standalone GRASS 6.4.3. I get  "ERROR: The 'make' program is required. Please install first."

There is also mention in the email thread above that there is a readme file with instructions on how to compile addons for OSX but that readme isn't included in the Kyngchaos.com download as mentioned and I can't otherwise seem to find it.
