setting MACOSX_DEPLOYMENT_TARGET=10.4 or MACOSX_DEPLOYMENT_TARGET=10.3 on an Intel Leopard produced binaries executable on Intel Tigers (we have no Intel Panther, though)
Without MACOSX_DEPLOYMENT_TARGET binaries from Leopard yield "Bus Error" on Tiger. The binary was built using my own binary-dist for Intel Tiger (Mac OS 10.4) (with GMP and GNUreadline frameworks).
