Thanks for posting your comments and issues to this ml.

These warnings should not do any harm, they are just a bit annoying.

the psyco initialisation warning does not relate to this

It looks like you don't have a
/home/family/.blender/scripts/brad/brad/tmp/
directory.
Make sure to create it.

Just make sure that you use units consistently in your file.
For instance I always use metres.
So if I get a model in millimetres, I scale it down with a .001 factor.
Then ies2rad by default outputs geometry and photometries using meters
(-dm), so I have no problems.
Perhaps you're trying to use the desktop radiance luminaires?
They are in foot, if I remember well, so you must scale them
appropriately, and redo the ies2rad run to get the photometries right.

Francesco
