How to set the environmental variable LD_LIBRARY_PATH in linux

Question

I have first executed the command: export LD_LIBRARY_PATH=/usr/local/lib

Then I have opened .bash_profile file: vi ~/.bash_profile

For some reason no one has mentioned the fact that the bashrc needs to be re-sourced after editing. You can either log out and log back in (like mentioned above) but you can also use the commands: source ~/.bashrc or . ~/.bashrc.
