You're right, it's defined there, for example:
const CovariantVector<float, 2>  NumericTraits<CovariantVector<float,
2> >::Zero = CovariantVector<float, 2>( NumericTraits<float >::Zero );

Okay, I do find this a bit strange:

cpbotha at MEEP /c/build/Insight-VS71/Code/Common/ITKCommon.dir/RelWithDebInfo
$ nm itkNumericTraitsCovariantVectorPixel.obj  | grep NumericTraits |
grep V\?\$CovariantVector\@M\$01 | grep Zero
00000900B?Zero@?$NumericTraits at V?$CovariantVector at M$01 at itk@@@itk@@2V?$CovariantVector at M$01 at 2@B

So it finds the symbol we're looking for, but then:

cpbotha at MEEP /c/build/Insight-VS71/bin/relwithdebinfo
$ nm ITKCommon.lib  | grep NumericTraits | grep
V\?$CovariantVector\@M\$01 | grep Zero

it seems that that module is not linked in somehow, or that the
symbols somehow get lost!  Checking the CMakeLists.txt file, it really
should be linked...

The complete options of the linker are as follows (this does not
include all object files it seems):
