Playing daisy in Linux?

[Hart Larry]

Well, maybe 3weeks ago I finally can enjoy NFB-News-Line, but I wanted to try 
out reading or listening to these daisy files, so I install a daisy player here 
in Debian.  I put all the content, mostly .xml and .smil files in a daisy 
directory.  If I run daisyplayer without any arguments, I get a boing from my 
sound-card, but if I provide a full path, I get pages of traceback errors-and-I 
must type reset.  Anyway no sound.  So can some1 please tell me the secret to 
playing these-and-thanks in advance
