ZeroMQ Java Binding LD_LIBRARY_PATH

[weaddecom]

I'm trying to use ZeroMQ on CentOS.I followed the install instructions for unix like platforms (http://www.zeromq.org/bindings:java)I keep getting the following exception when running:\[code\]java.lang.UnsatisfiedLinkError: no jzmq in java.library.path\[/code\]However the following line fixes this problem:\[code\]export LD_LIBRARY_PATH=/usr/local/lib \[/code\]What exactly is this LD_LIBRARY_PATH and why is not explained in the install instructions? Do I need to run this export everytime?
