Man Wreck Mac OS

Hi,
I'm very new to the matlab. Recently, I have compiled the c-file into mex file through the make file and after having been through all trouble compile the source code into the object and link them, the mex file crash.
I'm using Intel Macbook Pro, Mac OS X 10.5 and Matlab 7.4(2007a).
Here is the detail of the Makefile used for compile the c-file to mex file
****************************************************************************
#
# Unix/Linux Makefile for MATLAB interface to sba
#
MEX=/Applications/MATLAB_SV74/bin/mex
MEXCFLAGS=-I. -O #-g
# WHEN USING LAPACK, CHANGE THE NEXT TWO LINES TO WHERE YOUR COMPILED LAPACK/BLAS & F2C LIBS ARE!
LAPACKBLASLIBS_PATH=/Volumes/Research/Documents/PhD/CODE/SRC/lapack-3.1.1
#F2CLIBS_PATH=/usr/local/lib
# I had to specify the absolute path to the libs, otherwise mex linked against their dynamic versions..
INTFACESRCS=sba.c
INTFACESOBJ=sba.mexmaci
SBALIB=./libsba.a
LAPACKLIBS=$(LAPACKBLASLIBS_PATH)/liblapack.a $(LAPACKBLASLIBS_PATH)/libblas.a #$(F2CLIBS_PATH)/libf2c.a
# On systems with a FORTRAN (not f2c'ed) version of LAPACK, libf2c.a is
# not necessary; on others, libf2c.a comes in two parts: libF77.a and libI77.a
LIBS=$(SBALIB) $(LAPACKLIBS) #-ldl
dummy: $(INTFACESOBJ) projac.dylib
$(INTFACESOBJ): $(INTFACESRCS)
$(MEX) $(MEXCFLAGS) $(INTFACESRCS) $(LIBS)
projac.dylib: projac.c
gcc -fPIC -O3 -dynamic -dynamiclib -o projac.dylib projac.c
clean:
@rm -f $(INTFACESOBJ) projac.dylib
realclean cleanall: clean
depend:
makedepend -f Makefile $(INTFACESRCS)
# DO NOT DELETE THIS LINE -- make depend depends on it.
****************************************************************************
I have used the liblapack.a from my own compiled version. Also I have changed all of the projac.dylib from projac.so, since when it was .so file, it does not seem to be happy to compile at all.
With that makefile, the sba.mexmaci was compiled successfully.
But when I launch the function, the matlab crash and quit unexpected. I dont know how to launch the program in the linux command line, so I cant see the details of the bugs. But the Mac OS X automatically produced the report and here is the detail of the faults from the report.

Here is the link of the source code I have obtained from:
http://www.ics.forth.gr/~lourakis/sba/
And I have downloaded sba-1.4
Please help because I have stuck with this for so long and I really want to get the code to work in Matlab.
Any help would be most useful.
