Installing Mysql server in Home ..Do you already have another mysqld server running on port: 3306 ?

With a good amount of help on this forumn I have been able to Install Mysql server on my home directory

/home/myName/mysql

But whenevr I run the mysqld command to run the server I get the following error
******************
40901 18:27:36  Can't start server: Bind on TCP/IP port: Address already in use
040901 18:27:36  Do you already have another mysqld server running on port: 3306 ?
040901 18:27:36  Aborting

**********************

Is this because of the fact that there is already a mysql server running on my main machine..how should I work around this problem so that I can access the mysql server in my home directory

Please note that I dont have root previalges

Thanks for your time
