OSX : Symbols not found for architecture i386

I have the following makefile that uses C++ and OpenGL. It was compiling at all, so I added the -m32 line in order to attempt to get it to compile in x86_64. Now I'm getting the same error but it's saying i386 instead.

What can I do to get this program to compile?

I'm running OSX 10.8, just in case that makes a difference.

Thank you all.

.SUFFIXES: .cpp


#Change the following two lines to reflect the locations
# of the GLUT library (.a) and includes on your system

#TOP = /pool/u/class/cs520/Mesa-7.0.3
CFLAGS  = -w -s -O2 -ansi -DSHM
XLIBS   = -lX11 -lXext -lXmu -lXext -lXmu -lXt -lXi -lSM -lICE
LIBS    = -lglut -lGLU -lGL 
#INCLS   = -I/usr/X11R/include -I/share/mesa/include   #-I$(TOP)/include
INCLS   = -I/usr/X11R6/include -I/usr/X11/include/GL
LIBDIR  = -L/usr/X11/lib -L/usr/X11R6/lib #-L$(TOP)/lib 

#GLUT_LIB_LOCATION=/usr/X11R6/lib

#CPPFLAGS=-I${GLUT_INC_LOCATION} #-w 
#GLLIBS=-L${GLUT_LIB_LOCATION} -lglut -lGL -lGLU
#LPATH=${GLUTPATH}

libs =     ${GLLIBS}   -lm

    $(CC)   $(LPATH) tg.o tga.o terrain.o  -m32 ./glui/libglui.a $(libs) -o terrain  $(LIBDIR) $(LIBS) $(XLIBS)

.cpp.o:

clean:
    rm *.o

And I'm getting the following error.

You're compiling for MacOS X so don't use X11 but the native OpenGL Framework; the compiler/linker option is -framework OpenGL.

And the error you have stems from that you probably took precompiled library filed not even compiled for your particular version of MacOS X, if even MacOS X at all. No compiler switch will help you there.
