Ubuntu PHP-FPM not starting

I recently installed PHP 5.3.8 from source distribution on Ubuntu 11.04.

Here's the first parts of my configure directive:

./configure --enable-fpm --with-fpm-user=php-fpm 
--with-fpm-group=php-fpm --prefix=/usr/local/php-5.3.8 
--exec-prefix=/usr/local/php-5.3.8 
--with-config-file-path=/usr/local/php-5.3.8/etc 
--with-config-file-scan-dir=/usr/local/php-5.3.8/etc

Afterwards, I downloaded a sample for the shell script file that I used for /etc/init.d/php-fpm. I got the script from here: http://svn.php.net/repository/php/php-src/branches/PHP_5_3/sapi/fpm/init.d.php-fpm.in. I edited the file and added the paths to relevant locations and then I copied the contents to /etc/init.d/php-fpm.

I chmod +x php-fpm and then attempt to start it with ./php-fpm start and I get the following error:

Starting php-fpm [07-Sep-2011 02:55:34] ERROR: bind() for address '127.0.0.1:9000' failed: Address already in use (98)

I changed the listening port number in php-fpm.conf and I still get the same error.

One thing I noticed is that there doesn't seem to have been a php.ini file created. I've looked everywhere for it under my prefix php directory and other places. I'm not sure if this is what is causing the problem.

I'd appreciate any guidance on how I can get PHP working.

Thanks.

EDIT: This is what I get when I use the command: lsof -i -P

I'm not sure why they are so many though, I'll have to look at the php-fpm.conf.
