can't find shared libraries in gdb

[yinglcs@aim.com]

Hi,
I run my program under Gdb. But i get the following error saying it 
can't find the shared libraries:
(gdb) run
Starting program: /home/yinglcs/src/firefox1.5/dist/bin/firefox-bin
/home/yinglcs/src/firefox1.5/dist/bin/firefox-bin: error while loading 
shared libraries: libmozjs.so: cannot open shared object file: No such 
file or directory

But I check there is a soft link in the same directory as the 
executable and it points to a vaild file.
Can you please tell me how to fix this problem so that I can run my 
problem under gdb?

[yinglcs@localhost bin]$ ls -la libmozjs.so
lrwxrwxrwx  1 yinglcs yinglcs 24 Dec 15 09:47 libmozjs.so -> 
../../js/src/libmozjs.so*

[yinglcs@localhost bin]$ ls -la ../../js/src/libmozjs.so
-rwxrwxr-x  1 yinglcs yinglcs 1845285 Dec 15 09:47 
../../js/src/libmozjs.so*
