Is this a typo? You're passing the already processed eigenvectors 
through dteig again, nonsense would result.
pdview -datadims 256 256 70 -inputmodel dteig < 
camino_analysis/Eigen.Bdouble
Also, I don't know what the right -datadims for your data should be, but 
using -scalarfile with a header file might help to rule out a mismatch.

Final observations, your example has multiple calls to dtfit, you may as 
well just fit once:
dtfit camino_analysis/DTI_ec_VoxelOrder.Bfloat 
camino_analysis/bvec_rot.scheme > camino_analysis/DiffTensor.Bdouble
fa < camino_analysis/DiffTensor.Bdouble > camino_analysis/FA.Bdouble
dteig < camino_analysis/DiffTensor.Bdouble > camino_analysis/Eigen.Bdouble
Also, unless you only need a quick fitting for visualisation, any of the 
other models would be preferable to the simple linear dtfit.
