It's here: http://svn2.assembla.com/svn/pnh/
That's my personal gentoo overlay in which you'll find ebuilds that I created myself (you can find them on this site) as well as ebuilds that I copied from others.
Use it at your own risk.
For those who has not got layman, you need to emerge layman first:
[code]emerge -av layman[/code]
Now you're ready to add my overlay:
[code]layman -o http://phamngochai.net/myfiles/overlay/pnh.xml -a pnh[/code]
And that's it.
If you get an error, then this may work:
[code]layman -o http://phamngochai.net/myfiles/overlay/pnh.xml -L
layman -a pnh[/code]
Remember to run
[code]layman --sync ALL[/code]
to get the lastest ebuilds from overlays.

In case all those commands above dont work for you, you may want to try:
[code]layman -o http://phamngochai.net/myfiles/overlay/pnh.xml -s -a pnh[/code]
