Arduino application undefined reference for normal functions

I am trying to build model files that were initially created using 2011b with 2012b. I set up the arduino package and everything appears be good with my install. The build fails when I have either a floor function block, power block, or a mat script in my model. If I take those components out, the model builds, compiles, and flashes the device normally. When the process attempts to link the application, it appears to be missing some references. These c,h, and o files appear in the sharedutilities directory.

What could be causing this?

The build process will terminate as a result.

This has to do with model references. When I take the content out of the reference model, and try to use it right in the top level model, it works.
