[GRASSLIST:1109] Re: Error compiling on Mac OS X

Andy, I think a better configure line may be (for Grass 5, beta 8):

  ./configure -host powerpc-apple-nexstep3

(the CVS snapshot version recognizes OS X as powerpc-apple-darwin1.2)

Note that I have successfully compiled most of the source code for 
MacOS X and will make a compilation guide and binaries available 
soon.  Right now I am trying to get the X-windows based GUI working, 
which I am confident I will get working.

In all just 27 modules failed to build, and I will soon send an email 
of detailed errors to the development team for analysis.

As Markus stated, the Mac does not need the math library flag (-lm) 
in addition to removing the -lm switches from the src/CMD/head/head 
file, I also removed them from src/CMD/head/head.in, 
src/CMD/utils/setup, src/CMD/utils/setup.ig, 
src/CMD/utils/setup.xgrass.

Some of the files have the -lm switch up to three times - remove them 
all - or at least I did.
