[GRASS-dev] Re: proposal for grass extensions and addons

[William Kyngesburye]

This looks familiar from when I first noticed the makefile bits  
getting installed.  I work around most of it in my OSX modbuild setup  
by modifying grass.make and platform.make.

It would be nice to get it cleaned up and working - no need for my  
OSX hack.

A big problem I see is that INST_NOW.  That's just what I need to  
avoid for the OSX app build - installing (or building) into the  
binary distribution.  I avoid that in my modbuild by having a local/ 
external copy of the makefile bits in a folder layout like the  
source, so modules get built into the local distdir.
