[Insight-developers] ITK on Mac OX 10.2

[Bill Hoffman]

We are making some progress with ITK building on the latest Mac OS X version.
Numerics and VNL are now passing all the tests.   ITK is now the road block.
It would seem that they do not support weak data symbols, just functions.  So,
the static data members of templated classes cause duplicate symbols.
Perhaps we could try to remove any static data members of templated classes.

One of these StaticSpacing does not seem to be used except in the base class
of itkImageBase::GetSpacing which always seems to be overridden by child classes.
