Sorry for the delay in responding, I wanted to try every permutation that I 
could think of.  I updated the tracula binaries for snow leopard 
(https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-August/019946.html)
 and that gives me some of the same, and some different issues that may help.  
First, if the bvec file is in the correct format (3 columns), then it copies 
the file correctly and trac-all continues smoothly.  If the file is in the 3 
row format (needing to be transposed), then tracula will only copy the first 9 
numbers out of it giving the error of not having the correct number of bvecs to 
bvals.  So that seems fixable, I just need to reorient all of our bval and bvec 
files into the correct format.  

I'm still a bit unsure why tracula won't create the bvec and bval files during 
the mri_convert stage.  I have been using dcm2nii to create these two files but 
then continue to give tracula the path to the dicom files.  So the orientation 
of this file could be related to how dcm2nii writes the files.  Any suggestions 
would be very welcome.  As it stands, my current workflow is:

1. use dcm2nii to create bvec and bval files
2. reorient bvec and bval files to be 3 column and 1 column format respectively.
3. run trac-all -prep with a config file showing where the dicom images are and 
hand specifying the bvec and bval files
