How can I override the version of the C library loaded by a compiled program without source with no root access?

I have a compiled C program that implicitly attempts to load libc.so.6 when run. When I attempt to run it on a host that I do not have root access to, it complains that it needs a newer version of libc than is present. The host has a symbolic link from /lib/libc.so.6 to /lib/libc-2.3.2.so* and I placed a copy of libc-2.6.1.so in my filespace, made a symbolic link libc.so.6 to it and set LD_LIBRARY_PATH to the absolute path to the directory containing such, and ran the program again, receiving the same complaint. Is there any way to convince it to load the library in my filespace and not the system one that I cannot touch?
