There was a bug in the SignedDanielssonDistanceMapImageFilter a while 
ago. And the unmatched function call you have:

...
itkMorpholgyImageFilter.txx 62 error no matching function for call to
itk:ImageRegion<3>::PadByRadius(const itk::Size<2>);
...

The bug was that binaryball structuring element was hardcoded for 2D rather than use the input image dimention.....
And this filter derives form MorphologyImageFilter

cvs diff -r 1.6 -r 1.5 Code/Algorithms/itkSignedDanielssonDistanceMapImageFilter.txx

Can you please check on this. Most likely this is not the reason cause I put this filter in *after* ITK-1-8. (the version you seem to be using ! ). So I wonder if similar bugs have lingered around in other filters...

thanks
