This is talking about creating a local portage overlay for your own
ebuilds.  You can set PORTDIR_OVERLAY=/usr/local/portage in
/etc/make.conf, and then create your own portage tree under
/usr/local/portage [1].

You really should not mess with overlays unless you really know what
you are doing.  However, you generally start by either:

1. Copying an existing category/package directory from the official
tree, and hacking on it your overlay.  This is useful if you want to
do a version bump or apply a patch that is not in the offical tree.

2. Creating your own category/package directory, and adding your own
ebuilds and/or patches.

Once you have created your ebuild, "ebuild <path_to_ebuild> digest"
will generate the MANIFEST and other necessary files.

However, dev-lang/ifc already exists.  If you want the latest 9.0.031
version, you'll have to accept the ~arch keyword, but this is
certainly a lot easier than trying to maintain your own overlay.
