How do I make Lensfun work inside Gimp/Ufraw automatically?

[Walter Dnes]

  I posted sample images in a thread at
http://www.dpreview.com/forums/post/51971607 showing the distortion in
the raw file. There's a posting at http://www.gerhard.fr/DAM/lensfun.php
which lists parameters for the Canon S100.  I followed the instructions,
but it doesn't do anything.  Is there an additional step to "register"
the specs with Gimp/Ufraw?
