I have all the packages, but your information was very helpful.  I  
found my magic.mgc file and pointed horde to it, and it works.   
(Surprising it is in a different location on debian as compared to  
Ubuntu... the gap between the two seems to be widening to quite an  
extent now...).

Thanks for that!
