Buildout Error on CentOS

[kofi]

Hello

I just installed my first Plone in "zeo mode". However, after updating buildout.cfg I am receiving the message " Couldn't open /root/buildout.cfg" when I try to run "sudo /usr/local/Plone/zeocluster/bin/buildout -n". Can somebody help me here.

Thanks

Additional details:

Plone is installed at /usr/local/Plone
buildout.cfg is at /usr/local/Plone/zeocluster/buildout.cfg
buildout is at /usr/local/Plone/zeocluster/bin

Thanks
