 Hi,sorry about the delay of the answer,I'd been very busy.
 First of all tank you  very much for interesting in my message,I 
couldn't imagine to have a response from the main developer of one of 
the best things made for Linux-Audio,and excuse my english.

     I'm very newbie in this kind of linux tasks,and try to learn as 
much as I can.
     I'm trying to build my own audio-system and compile only the more 
ussual  apps for me;Ardour and Jack are the main core of this.By now I 
take the Demudi kernel till I learn to compile my own,and compile with 
succes Ardour and some other apps.Before try to compile jack I installed 
it from Sid  and everythings works fine  but the message that shows at 
the window messages, that doesn't  have influence  with the normal 
function of jackd.

  Ok it will be present in the future.

>when you recompiled JACK, did you remove the old version first?
   I did many things in the procces and probably no.At the second time I 
remove all about jack and try again.But if I remove the compilation 
installed and do an apt-get install jackd,everything goes back to the 
fine working but the "cannot write to jackstart sync pipe 4 (Bad file 
descriptor)" message return.

  First I did --prefix=/usr    and later leave blank to use the default 

  Now I'm at the begin again,I removed all the jack staff and have the 
source code to try to compile.I will read more about this and see what 

 Again thank you very much for your interest.
