Add an ebuild in portage :
- create the directory /usr/local/portage
- add in the file "make.conf" this : PORTDIR_OVERLAY="/usr/local/portage"
- create in the directory /usr/local/portage a sub-directory for the category, for example games-misc if you choose fortune-mod-french-0.02
- create an other sub-directory with the name of the ebuild (without the version number) for example fortune-mod-french
- copy or download the ebuild in this new directory (and if needed the other files in the sub-directory "files")
- Enter this command : ebuild lenomdelebuild.ebuild manifest, for example : ebuild fortune-mod-french-0.02.ebuild manifest
The ebuild is now in the portage tree.
