Problems calling S-Plus help

[Riccardo Gusso]

Hello,
after a little bit of work I have been successful in installing Splus and ess 
on my laptop equipped with Debian Linux. 
However, I have still some problems when I try to see the help for an Splus 
function from the Splus process running inside Xemacs: for example if I give 
as input 
'?princomp' 
I get as answer
'>emacsclient: can't find socket; have you started the server?'

Everything instead is ok if I give the same input from Splus command window.
Can anybody help me to solve this problem?
Thanks in advance,
                          Riccardo Gusso
