The MacPorts project is pleased to announce that prebuilt archives for OS X 10.11 El Capitan are now available for many ports, and will be used automatically when installing. These join our existing prebuilt archives for OS X 10.6, 10.8, 10.9 and 10.10. (The building of binaries for OS X 10.7 is temporarily suspended but will resume.) A prebuilt archive cannot always be used, for a number of reasons: * Our archives are built only for the default prefix (/opt/local), so if MacPorts is installed in a custom prefix, it will not download them. This also applies to applications_dir (/Applications/MacPorts) and frameworks_dir (${prefix}/Library/Frameworks). * We only build archives for the default variants of each port. * Some ports have a license that does not allow for distribution of binaries, or have a license that conflicts with the license of a dependency in a way that prevents such distribution. * Some ports do not indicate their license, so we do not distribute archives of those ports. -Ryan
