Here it is:

gcc -I/usr/src/grass5.0.0pre4/src/include -O2 -no-cpp-precomp 
-D__unix__   -I.   -c geod.c -o OBJ.powerpc-apple-darwin5.4/geod.o

I have actually ran into this quite a few times building various 
pacakges, and it is just a matter of the order of the includes, or not 
the right ones included.

Negative, there was no error building libgeo.

Linking in "vars.o" fixed the problem. I realize it is abit of a hack 
but it seems to work:

gcc -L/usr/src/grass5.0.0pre4/src/libes/LIB.powerpc-apple-darwin5.4 -o 
/usr/src/grass5.0.0pre4/dist.powerpc-apple-darwin5.4/etc/geo.point 
OBJ.powerpc-apple-darwin5.4/bin_point.o OBJ.powerpc-apple-
darwin5.4/vars.o LIB.powerpc-apple-darwin5.4/libgeo.a -lgis -llock 
-I/usr -lz

Thanks for the info and all of your help.

I now have successfully built 100% of the modules Pre4, and I am 
currently uploading the binaries. Markus: I will email you when it is 
done uploading.

I just read the fix about the "make install" bug, and it installed just 
fine, and everything seems to work so far.

However, it did complain that I did not set the GISDBASE environment, 
which I have not needed to set it before. Once I set it everything seems 
ok.

Also, when I quit Grass, I select the "close all X windows" option, and 
all the windows and menus close, except for the actual monitors.

Note that I also had to change "<malloc.h>" to  "<sys/malloc.h>" for 
main.c in r.sun and for main.c, dataoct.c, oct.c, user2.c, user4.c in 
s.vol.rst.

I had to add "-liconv" in src/display/d.text.freetype.

And I had to:

Or else I got:
