I then start the distccd using "/home/local/distcc/bin/distccd --daemon --log-file=/var/log/distccd.log --listen 127.0.0.1 --allow 192.168.10.95" I then get the error in the log file:

check for /etc/xinetd.d/distccd or similar. inetd or xinetd could be 
"holding" that port for you but with incorrect flags to have distccd work.
alternatively some other program has misassigned that port to itself, 
try netstat -n to see if that port is listed.
