Trying to build the LEVMAR math library on a mac using the Accelerate Framework

Question

Hello.
I want build levmar-2.5 math library on a mac using the included Makefile. It requires LAPACK,
another math library which is included in the Accelerate Framework. I do not know how to modify
the Makefile to indicate the location of the library so that it builds correctly. There is a
libLAPACK.dylib in the framework. Ultimately, I will want to use this library to build another library. Also I am not sure if there will be a problem mixing .so and .dylib dynamic libraries.
Thank you.

The project is located at levmar.

Here is the Makefile:

#
# Unix/Linux GCC Makefile for Levenberg - Marquardt minimization
# Under windows, use Makefile.vc for MSVC
#

CC=gcc
CONFIGFLAGS=#-ULINSOLVERS_RETAIN_MEMORY
#ARCHFLAGS=-march=pentium4 # YOU MIGHT WANT TO UNCOMMENT THIS FOR P4
CFLAGS=$(CONFIGFLAGS) $(ARCHFLAGS) -O3 -funroll-loops -Wall #-ffast-math #-pg
LAPACKLIBS_PATH=/usr/local/lib # WHEN USING LAPACK, CHANGE THIS TO WHERE YOUR COMPILED LIBS ARE!
LDFLAGS=-L$(LAPACKLIBS_PATH) -L.

                             # On systems with a FORTRAN (not f2c'ed) version of LAPACK, -lf2c is
                             # not necessary; on others, -lf2c is equivalent to -lF77 -lI77

You need to pass -framework Accelerate to gcc. You also need to#include <Accelerate/Accelerate.h>. Details are here.
