Ok, that makes sense to me.  I tried to see what the current value is by doing
	echo $LD_LIBRARY_PATH
but it told me that the this is an "Undefined variable."  That seems strange to me.  I am running on a RHEL4 cluster with a C-shell.  I tried to do 
	setenv LD_LIBRARY_PATH /home/jhtu/local/lib:${LD_LIBRARY_PATH}
and of course got the same error about an undefined variable.

I'm not sure what this means.
