Looks to me like all that is to set it up for testing and debugging. If you just want to use it, you could probably just configure it from cmake to build with make instead of xcode (follow the linux instructions). > Before I start however is there an easier way to do this?

Lots of overhead, and it can interfere with compiling other software from scratch. They don't use my frameworks, so if you are using my GRASS binaries you will be duplicating all those libraries (GDAL, Geotiff and their dependencies). Boost could be trouble, it looks like liblas uses boost libraries (boost is by default a header-only library). Making a package has crossed my mind, though I was waiting for it to mature (this was a while ago) and I've been distracted by other things... At least, when I start looking at it I will add build instructions (hopefully simpler) to my site. ----- William Kyngesburye <kyngchaos*at*kyngchaos*dot*com> http://www.kyngchaos.com/ "Mon Dieu! but they are all alike.
