wodim:Can't Set SG_SET_TIMEOUT

["Thomas H. George" <lists@tomgeorge.info>]

I have an Etch box with a linux-image-2.6.18-5-k7.  All works well but

   wodim -devices
   Beginning native device scan.  This may take a while ...
   wodim:  Invalid argument.  Cannot Set  SG_SET_TIMEOUT

Apt-get install wodim confirms I have the latest release.  I have also 
run apt-get dist-upgrade but still get the same result from wodim -devices.

What's wrong?
