Installed how is the usual question: from sources or an RPM?

This is something that is set up when R is configured, and stored in 
R_HOME/etc/ldpaths.  Has perchance your Java subsystem been updated since 
R was installed?  In which case update R_HOME/etc/ldpaths as appropriate, 
or set R_JAVA_LD_LIBRARY_PATH (not LD_LIBRARY_PATH) to override the 
setting there.
