Fedora :: Boost Libraries Not Found

I installed Boost 1.43.0 on Fedora 12 32 bits, using standard build from the source code procedure:

./bootstrap.sh
./bjam
./bjam install

I see all Boost libraries in /usr/local/lib. Now I build my own program depending on the Boost libraries, and it is built successfully. However, when I try to execute my program, it shows "Library not found" message:

Code:
[alex@localhost ~]$ sixfpdconsole

sixfpdconsole: error while loading shared libraries: libboost_system.so.1.43.0: cannot open shared object file: No such file or directory

[alex@localhost ~]$ ldd /usr/local/bin/sixfpdconsole
