Error: OE-core's config sanity checker detected a potential misconfiguration...Do not use Bitbaker as root.

Hi,
I was trying to install the cross-complier by going through the instructions given in http://wp.angstrom-distribution.org/building-angstrom/

I got the error (title of this thread) when running this command line

$ MACHINE=beaglebone ./oebb.sh bitbake virtual/kernel

I had done the following updates
$ git pull
$ ./oebb.sh update

My OS is Ubuntu 12.04 LTS

Any help is appreciated.
