    This error message is an indication that was not found in the 
    default library search path,  nor in a directory listed in the 
    LD_LIBRARY_PATH variable.
    The BLCR installation instructions in the BLCR_Admin_Guide have always 
    recommended setting LD_LIBRARY_PATH if BLCR is not installed to a prefix 
    of /usr or /usr/local.  However, until recently the cr_run script worked 
    even when LD_LIBRARY_PATH is not set, because it used  the full path to in the LD_PRELOAD environment variable.  In order to support 
    both 64- and 32-bit applications on x86-64 with a single cr_run script, 
    the full path was replaced with just the filename component, making the 
    setting of LD_LIBRARY_PATH no longer optional.
    Let me know if setting LD_LIBRARY_PATH does not correct your problem.
