How should I tweak LD_LIBRARY_PATH?

[red floyd]

OS: RHEL 3 WS
Compiler: gcc (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-49)
Problem: I installed Matlab R14SP2, and adjusted my LD_LIBRARY_PATH as 
they specified in their install manual.

Now, when I throw exceptions, they are never caught, and terminate() is 
called instead.  The problem is in the MATLAB version of libstdc++.so.5
($MATLAB/sys/os/glnx86/libstdc++.so.5 -- where $MATLAB is the 
installation directory).

What is the best way to set my LD_LIBRARY_PATH so that I get the stock 
libstdc++?
