Install DFF on Gentoo

Install DFF on Gentoo Using ebuild
You can use layman to add the pentoo overlay which contain the ebuild, thanks to ikelos and pentoo team providing it ! Have a look at their trac for latest DFF version supported and changes comments.
If you don't have layman installed:

#> emerge layman

#> echo "source /var/lib/layman/make.conf" >> /etc/make.conf

Then add the pentoo overlay :

#> layman -a pentoo

Then you can emerge DFF and it's dependencies. DFF ebuild is masked for some architecture so, for example on x86 don't forget to unmask :

ACCEPT_KEYWORDS="~x86" emerge dff

or on an amd64 compatible architecture :

ACCEPT_KEYWORDS="~amd64" emerge dff
