What is the correct value for LD_LIBRARY_PATH on 64-bit Linux when using MATLAB Compiler 4.4 (R2006a)?

The MATLAB Compiler documentation lists the following to set my LD_LIBRARY _PATH variable.

 setenv LD_LIBRARY_PATH 

 $MATLABROOT/sys/os/glnxa64: 

 $MATLABROOT/bin/glnxa64: 

 $MATLABROOT/sys/java/jre/glnxa64/jre1.4.2/lib/amd64/native_threads: 

 $MATLABROOT/sys/java/jre/glnxa64/jre1.4.2/lib/amd64/client: 

 $MATLABROOT/sys/java/jre/glnxa64/jre1.4.2/lib/amd64:

$MATLABROOT is the MATLAB root directory on your machine, as returned by typing:

matlabroot

at the MATLAB command prompt.

However, there is no folder named:

 $MATLABROOT/sys/java/jre/glnxa64/jre1.4.2/lib/amd64/client:

When I executed my application with the LD_LIBRARY_PATH variable set to the above value, I receive the following error message.

 Warning: Unable to load Java Runtime Environment: libjvm.so: cannot open shared object file: No such file or directory. 

 Warning: Disabling Java support 

 Hello, World 

 Severe:

 The program '[12467] : Native' has exited with code 2 (0x2).

There is an error in the documentation for MATLAB Compiler 4.4 (R2006a) with regards to the value of the LD_LIBRARY_PATH environment variable on 64-bit Linux platforms.

On a development machine, the documentation should read:

 setenv LD_LIBRARY_PATH 

         $MATLABROOT/sys/os/glnxa64: 

         $MATLABROOT/bin/glnxa64: 

         $MATLABROOT/extern/lib/glnxa64: 

         $MATLABROOT/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/native_threads: 

         $MATLABROOT/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/server: 

         $MATLABROOT/sys/java/jre/glnxa64/jre1.5.0/lib/amd64 

     setenv XAPPLRESDIR $MATLABROOT/X11/app-defaults

For a deployment machine, the documentation should read:

 setenv LD_LIBRARY_PATH 

$MCR_ROOT/$VER/runtime/glnxa64: 

$MCR_ROOT/$VER/sys/os/glnxa64: 

$MCR_ROOT/$VER/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/native_threads: 

$MCR_ROOT/$VER/sys/java/jre/glnxa64/jre1.5.0/lib/amd64/server: 

$MCR_ROOT/$VER/sys/java/jre/glnxa64/jre1.5.0/lib/amd64:

 setenv XAPPLRESDIR $MCR_ROOT/$VER/X11/app-defaults

In the preceding example, $MATLABROOT and $MCR_ROOT represent the root directories of the MATLAB ($MATLABROOT) and MATLAB Compiler Runtime (MCR) installation ($MCR_ROOT) respectively. $VER refers to the version of MCR installed (for example, v73 or v74).
