Jeshua,

OK, I have fixed it up so it builds fine from source now. Could you test
/Users/frankw/gdal/libgdal.1.1.dylib with GRASS's r.in.gdal and see if it
works? You can set your DYLD_LIBRARY_PATH to point to the directory and
it will hopefully work. If not, let me know (and where your GRASS build is).

I have put this build on my GRASS page, so if it works we can proceed to
announce it.

Thanks Frank!

I installed your gdal lib, and when attempting to compile r.in.gdal, I get a "Undefined symbols:
_GBGetSymbol" error.

Any ideas?

Here is the full-related message:

gcc -o /usr/src/grass/dist.powerpc-apple-
darwin1.3.3/etc/bin/cmd/r.in.gdal OBJ.powerpc-apple-darwin1.3.3/main.o OBJ.powerpc-apple-darwin1.3.3/gbgetsymbol.o OBJ.powerpc-apple-

src/raster/r.in.gdal/gbgetsymbol.c contains two definitions of
GBGetSymbol(); one definition is conditional upon

  #if defined(__unix__)

while the other is conditional upon

  #ifdef _WIN32

It appears that neither of these macros are defined on your system
(clearly it's the first one which should be). The simplest workaround
is to add "-D__unix__" to CFLAGS (e.g. by adding it to COMPILE_FLAGS
in src/CMD/head/head.<platform>).
