backward compatibility issue

I have been trying to get VCS to run with Fedora Core 3. Since VCS was
supporting enterprise 3.0. I took the compat-gcc and compat-glibc source
rpms from enterprise 4.0 and built them with the fedora libs. That
worked so I then installed them which also worked. I then added -
L /usr/lib/i386-redhat-linux3E/lib to the link line for VCS. 
But I still get the same link error as without the compat libs. See
Below. Anyone know what I have done wrong??
Thanks
