OK, I have downloaded the source and looking at debian/rules file (which 
seems to have been written by someone called Jelmer Vernooij (where have 
heard that name before ?)) I think I need to add '--enable-debug' to the 
'conf_args' list, but there is also this:

         # add debug symbols for all samba packages to the same debug 
         dh_strip -a --dbg-package=samba-dbg

Do I need to do anything with this ?
