You need to set the DYLD_LIBRARY_PATH environment variable.

From the dyld man page:

      This  is  a  colon  separated  list  of directories that contain libraries. The dynamic linker
      searches these directories before it searches the default locations for libraries.  It  allows
      you to test new versions of existing libraries.

      For  each  library  that  a program uses, the dynamic linker looks for it in each directory in
      DYLD_LIBRARY_PATH in turn. If it still can't find the library,  it  then  searches  DYLD_FALL-
      BACK_FRAMEWORK_PATH and DYLD_FALLBACK_LIBRARY_PATH in turn.
