Just wanted to let you know that we solved the problem. I have detailed the steps below:

1.) The need for the "GPT Disk Label" was still there but we worked around the problem by first choosing one of the default setups for RHEL6. We let the default-setup format and prepare the file-system as it pleased and I am guessing that it created a "GPT Disk Label" for our disk.

2.) Once it had created and formatted the partitions, we just canceled the setup and rebooted the server. At this stage, my guess would be that the RHEL6 setup did everything that was necessary to prepare the file-system -- including creating a "GPT Disk Label".

3.) After rebooting, we simply entered setup again and choose the 'custom installation' and created partitions according to our specifications.

4.) Hitting the next button did the trick and we got to the next stage of installation.

Thanks for everyone for helping out...
