To approximate what the apt-get client actually does; first download "http://content.runescape.com/a=946/downloads/ubuntu/trusty/Release"; (URL given + distversion + "/Release); note the MD5/SHA1/SHA256 checksums. Download the 64-bit Packages file from "http://content.runescape.com/a=946/downloads/ubuntu/dists/trusty/non-free/binary-amd64/Packages";, this will give the name/version/dependencies for every package distributed from that repo. From that file, find the "Filename:" field, append that directly to the URL they gave, so "http://content.runescape.com/a=946/downloads/ubuntu/pool/non-free/r/runescape-launcher/runescape-launcher_2.2.2_amd64.deb";. This file declares the following dependencies: Ubuntu Gentoo Equivalent libsdl2-2.0-0 (>= 2.0.2+dfsg1-3ubuntu1.1) >=media-libs/libsdl2-2.0.2 [This doesn't appear to actually be used by the executable] libglew1.10 (>= 1.10.0-3) >=media-libs/glew-1.10.0:0/1.10 [This doesn't appear to actually be used by the executable] libc6 (>= 2.19-0ubuntu6.6) >=sys-libs/glibc-2.19 libcurl3-gnutls (>= 7.35.0-1ubuntu2.5) >=net-misc/curl-7.35.0 libstdc++6 (>= 4.8.4-2ubuntu1~14.04) >=sys-devel/gcc-4.8.4[cxx] libgcc1 (>= 1:4.9.1-0ubuntu1) >=sys-devel/gcc-4.9.1 libvorbisenc2 (>= 1.3.2-1.3ubuntu1) >=media-libs/libvorbis-1.3.2 [This doesn't appear to actually be used by the executable] libwebkitgtk-1.0-0 (>= 2.4.8-1ubuntu1~ubuntu14.04.1) >=net-libs/webkit-gtk-2.4.8:2 (I think) The package also depends on the following shared libraries, not exposed above: dev-libs/glib:2 libglib-2.0.so.0 libgobject-2.0.so.0 media-libs/libpng:1.2 libpng12.so.0 x11-libs/libXxf86vm libXxf86vm.so.1 x11-libs/gtk+:2 libgdk-x11-2.0.so.0 libgtk-x11-2.0.so.0 x11-libs/gdk-pixbuf:2 libgdk_pixbuf-2.0.so.0 x11-libs/libX11 libX11.so.6 x11-libs/cairo libcairo.so.2 x11-libs/libSM libSM.so.6 x11-libs/pango libpango-1.0.so.0 libpangocairo-1.0.so.0 To extract the .deb, if you don't have dpkg installed, you can use `ar x ./runescape-launcher_2.2.2_amd64.deb data.tar.xz` to get a tarball named "data.tar.xz" that contains the actual binary package. Note that the only thing that was really Gentoo-specific in the above was the mapping of libraries to package names/slots/versions. Everything else is "Generic Linux amd64" :). -- Jonathan Callen
