Everything on OSX is prefixed DYLD, not LD. And they change the names a bit.. I think what you want is:

DYLD_INSERT_LIBRARIES

This is a colon separated list of dynamic libraries to load before the ones specified in the program. This lets you test new modules of existing dynamic shared libraries that are used in flat- namespace images by loading a temporary dynamic shared library with just the new modules. Note that this has no effect on images built a two-level namespace images using a dynamic shared library unless DYLD_FORCE_FLAT_NAMESPACE is also used.
