spamc 3.1.1 and procmail

[".rp" <pr...@moveupdate.com>]

Hi,

In our system wide .procmail I have been using /usr/bin/spammassin. Recently the 
CPU usage has soared when spamassassin ran so I decided to use /usr/bin/spamc 
with spamd running as a dameon. 

well, it didn't quite work. here is a sample problem:
| /usr/bin/spamc -u $LOGNAME


 sendmail[21908]: l19HQGne021908: from=<bounce-422420-
1377318@lists.now.org>, size=18119, class=0, nrcpts=1, msgid=<LYRIS-1377318-
422420-2007.02.09-08.29.35--xyzsom#xyz.com@lists.now.org>, proto=SMTP, 
daemon=Daemon0, relay=lists.now.org [198.65.157.134]
 spamd[17291]: spamd: connection from localhost [127.0.0.1] at port 56232
 spamd[17291]: spamd: setuid to xyzsom succeeded
 net spamd[17291]: spamd: creating default_prefs: 
/home/xyzsom/.spamassassin/user_prefs
 net spamd[17291]: mkdir /root/.spamassassin: Permission denied at 
/usr/lib/perl5/vendor_perl/5.8.0/Mail/SpamAssassin.pm line 1469
 net spamd[17291]: config: cannot write to /home/xyzsom/.spamassassin/user_prefs: 
Permission denied

I also tried spamc with no parameters but that did not help.
So what changes do I need to make? Will this adversly affect running 
/usr/bin/spamassassin ?
