solution to "error while loading shared libraries"

After I installed bonddb and tried to start bondfrontend for mrbounce project, I got the following error:

bondfrontend: error while loading shared libraries: libbonddb2.so: cannot open shared object file: No such file or directory

The solution is:
export LD_LIBRARY_PATH=/usr/local/lib
(or setenv LD_LIBRARY_PATH /usr/local/lib if you use tcsh)
