gnome interface

I have seen Gnome run with Mac OS X over at the screenshots link on ResExcellence ( I do not know how to install it other than know that you must have X Windows already installed on your computer. I installed Mac GIMP, which installed X Windows for me ( Upgrading from Mac OS X 10.0.4 to 10.1 disabled X Windows and I did not know how to get it running again. I found an "update" for XDarwin on versiontracker (htttp:// that re-enabled X Windows. After that I installed OroborOSX and it is very nice. This provides a nice way to get around X Windows. I would like to have Gnome installed, just don't know how to do it.
