Linking to a shared library

I'm trying to get Valgrind to work with an openmpi application in OS X. However I want to hardcode the path to a shared library called libmpiwrap-amd64-darwin.so into my application so that it is available at runtime. In Linux this is relatively simple, I would just add the option -Wl,"-rpath=/PATH_TO_LIB_FILE" to my compiler (mpicc). This doesn't work in OS X however. How can I hardcode the path into my executable?

libdl

libdl(3LIB)							Interface Libraries						       libdl(3LIB)

NAME

       libdl - dynamic linking library

SYNOPSIS

       cc [ flag... ] file... -ldl [ library... ]

DESCRIPTION

       Historically, functions in libdl provided for dynamic linking support. This functionality now resides in libc(3LIB).

       This  library  is  maintained  to provide backward compatibility for both runtime and compilation environments. The shared object is imple-
       mented as a filter on the runtime linker. See ld.so.1(1). New application development need not specify -ldl.

INTERFACES

       The shared object libdl.so.1 provides the following public interfaces. See intro(3) for additional information on shared object interfaces.

       dladdr			     dladdr1
       dlclose			     dldump
       dlerror			     dlinfo
       dlmopen			     dlopen
       dlsym

FILES

       /lib/libdl.so.1		       shared object

       /lib/64/libdl.so.1	       64-bit shared object
