For the most part I've gotten it to run fairly stable minus a few remaining issues with the gnome-keyring not working and gdm not working which are being worked on. Other than that I am very happy with it!! It's so nice to be able to use Gnome 3 with my existing PBI's, and the full suite of control panel tools, and the warden.
If anyone would like to try this I would recommend one of 2 options.
1.) install PCBSD with no window manager, and then use pkg_delete or pkg_deinstall to remove all gnome and libgnome ports. Otherwise you will run into dependancy hell when you try to install it. I chose option #1 so I could use an rdp session to another desktop using fluxbox to work while I was building ports.
Then download and run as root the marcuscom script after updating ports. Make sure you have kernel src installed.
fetch

sh ./marcusmerge -u -m ports -s /usr/src
2.) install FreeBSD and then build the PCBSD tools on top of it after installing x11 and gnome 3 and slim. I want to stay away from this subject right now as for me that falls out of the scope of this thread I think but here is a guide to give an idea of how to accomplish this.

For root on ZFS users I would recommend using snapshots at every turn for
/usr/ports/
/usr/ports/distfiles
/ROOT/default
/usr/home
