Library linking with GMP

I am trying to set up the gnu multiple precision arithmetic library for some c++ programming I have to do.
I am using a system with mac osx 10.6.3 and do NOT have root user access.
I'm trying to use gmp 5.0.1.
Since I don't have root user access, I had to install to a different directory
Thus I used

Code:

./configure --prefix=~/gmp --enable-cxx
make
make install

I also ran make check and it did not report any errors.

I then went to run a test program
Compiled with no errors using

Code:

g++ gmptest.cxx -I/Users/****/gmp/lib/ -I/Users/****/gmp/include/ -L/Users/****/gmp/lib/ -lgmpxx -lgmp -o gmptest

and tried to run with

Code:

./gmptest

The error I get is

Code:

dyld: Library not loaded: /usr/local/lib/libgmpxx.4.dylib
  Referenced from: /Users/****/./gmptest
  Reason: image not found
Trace/BPT trap

The gmptest.cxx test program is the following

Code:

#include <gmp.h>
#include <gmpxx.h>
#include <iostream>
#include <stdlib.h>
#include <stdio.h>
using namespace std;
void foo (mpz_t result, const mpz_t param, unsigned long n) 
{
unsigned long i;
mpz_mul_ui (result, param, n);
for (i = 1; i < n; i++)
	mpz_add_ui (result, result, i*7);
}

int 
main () 
{
mpz_t r, n;
 mpz_init (r);
 mpz_init_set_str (n, "123456", 0);
 foo (r, n, 20L);
 gmp_printf ("%Zd\n", r);
 return 0;
}

It's just some program I found that should print out a number.. Not important what it does at this point, I just want it to run.

I understand the error is saying that it cant find the libgmpxx.4.dylib file in /usr/local/lib which makes sense because it isn't there. But I thought the -L and -I settings I put in the compiler options tell it to look there for the libraries, and that library DOES exist there.

What am I doing wrong? Did I miss something?

Edit:
I also checked otool -L gmptest and it shows libgmpxx.4.dylib and libgmp.10.dylib linked from /usr/local/lib . They do NOT exist in this directory, they exist in /Users/****/gmp/lib where I thought I had told it to look.

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
