Builder JA problem in R2013b

I am using Builder JA in the R2013b version of MATLAB on OS X (10.9.1). I have a very simple MATLAB file that I want to convert to Java but am having run-time problems when calling the dicominfo method.

Using Builder JA I have the following MATLAB file (with DICOM-related methods isdicom and dicominfo):

function mask = ePAD_regiongrow( point, files, options )

    if (nargin >= 2)
      curfile = files(1);
      if (iscell(curfile))
          curfile = files{1};
      end
      if (isdicom(curfile))
          iminfo = dicominfo(curfile);
      end
    end

end

When I import this file into the builder it correctly adds dicomdict.m, dicominfo.m and isdicom.m to the "Files required for your application to run" section.

When deploy the resulting Java JAR I get a "Could not find dicom-dict.txt file" error so I manually added this to the required files area. (This seems like a bug?)

I regenerate the JAR and deploy again and now I get the following error:

com.mathworks.toolbox.javabuilder.MWException:Undefined function 'dicomparse' for input arguments of type 'char'.

I am deploying this to a CentOS machine with Java 7 runtime (1.7.0_51) and version R2013B of the MCR installed.

What I am missing?

Follow up: I installed MATLAB R2013b on a CentOS machine, generated the JAR, deployed the new JAR, and it now works. Is there a restriction that Builder JA must be run on the same architecture as the target deployment?

TIA
