You aren't linking your code against the ITKStatistics library.

If you are migrating from an older ITK distribution (such as ITK-2-2
pre) to the current one, you will need to link most Statistics programs
against the ITKStatistics library. 

This wasn't necessary before cause all the code in Statistics/ was
templated. Some of it was converted to .cxx files now.

For instance the CMakeLists.txt in Examples/Registration

  TARGET_LINK_LIBRARIES(ImageRegistrationHistogramPlotter 
                        ITKNumerics ITKIO ITKCommon ITKStatistics)




Does this help ?
