Terry Duell has written a tutorial describing a very simple 
technique for calibrating lens distortion parameters with hugin:

http://hugin.sourceforge.net/tutorials/calibration/

The advantage of this technique is that it doesn't rely on perfectly 
rectangular buildings or involve multiple overlapping photos taken 
with a panoramic head - Just a simple scene that anyone can 
construct.

The other advantage is that it has real potential for automatic 
processing.
