Hi! Currently bleeding-edge mc-9999.ebuild (git)
hosts on repo.or.cz in overlay format:

    git://repo.or.cz/slyfox-gentoo.git

In order to use it you need to perform some steps:

1. fetch overlay somewhere:
  $ cd ~/portage/
  $ git clone git://repo.or.cz/slyfox-gentoo.git

2. add overlay to your PM:
  * portage:
      $ cat /etc/make.conf | grep PORTDIR_OVERLAY
          PORTDIR_OVERLAY="/home/slyfox/portage/slyfox-gentoo"
  * paludis:
     $ cat /etc/paludis/repositories/slyfox-gentoo.conf
           location = ${ROOT}/home/slyfox/portage/slyfox-gentoo
           master_repository = gentoo
           format = ebuild

3. unmask unkeyworded ebuild:
  * portage:
      $ ACCEPT_KEYWORDS="~amd64 **" emerge -pv mc
      or
      $ cat /etc/portage/package.keywords | grep app-misc/mc
          =app-misc/mc-9999 ~amd64 **
  * paludis:
      $ cat /etc/paludis/keywords.conf.d/mc.conf
          =app-misc/mc-9999::slyfox-gentoo ~amd64 *

4. install ebuild the way you usually do it

5. update an overlay time to time:
     $ cd ~/portage/slyfox-gentoo
     $ git pull
