I build Pale Moon to my own custom specs, as well as a contributed
SSE-only build for older machines. At one point, I read the list of
necessary stuff to do the build. I incorporated the following into
/etc/portage/palemoon_build
>=app-arch/zip-2.3
>=dev-lang/perl-5.6
>=dev-lang/python-2.7.3
>=dev-lang/yasm-1.0.1
>=dev-libs/glib-2.24
dev-vcs/git
media-libs/fontconfig
>=media-libs/freetype-2.1.0
media-libs/mesa
=sys-devel/autoconf-2.13
sys-devel/gcc
<=x11-libs/gtk+-3.0
x11-libs/libXt
x11-themes/hicolor-icon-theme

I tried "emerge -pv --unmerge @palemoon_build", and it was ready to
delete all the stuff, including gcc, etc.

Kind of hard to "pull it back in" if gcc or glib or ncurses isn't
present. This is rather dangerous. The problem is that, unlike an
ebuild, "emerge --unmerge @set" removes all packages in the set,
regardless of whether they're required by another package or not.
I deleted /etc/portage/sets/palemoon_build, and the entry
"@palemoon_build" from /var/lib/portage/world_sets. It turns out that
all these packages are required anyways. hicolor-icon-theme was not
required previously, but <RANT> gtk seems to add more and more GNOME
dependencies every time I update my system. </RANT>
Let's say I try to do this as a meta package. So in my overlay I
create a category "meta-set" and a file "meta-set/pmbuild-0.ebuild"
EAPI=5
SLOT="0"
KEYWORDS="amd64 x86"
DEPEND="
>=app-arch/zip-2.3
>=dev-lang/perl-5.6
>=dev-lang/python-2.7.3
>=dev-lang/yasm-1.0.1
>=dev-libs/glib-2.24
dev-vcs/git
media-libs/fontconfig
>=media-libs/freetype-2.1.0
media-libs/mesa
=sys-devel/autoconf-2.13
sys-devel/gcc
<=x11-libs/gtk+-3.0
x11-libs/libXt
x11-themes/hicolor-icon-theme"
Does each entry have to be detailed with configure, install, etc,
stuff, or is this sufficient?
