There is at least 2 differences between your stuff and mine, 
 1- I'm using root 3.03.09
 2- My software is compiled with gcc 3.0.4

Now, it's true that other people (Peter, ...) don't have the same problem. 
You also used to run the stuff without problem in the past. My suggestion 
is to recompile your generate progs after having pointed your path and 
LD_LIBRARY_PATH to /afs/rhic/opt/brahms/new_gcc304/{bin,lib} :

in a csh shell, setenv PATH and LD_LIBRARY_PATH to these directories.
then go to you acceptance dir, make clean, then type :

make CC=gcc3 CXX=g++3 LD=g++3

Try again to run mrsgenerate.
