For Android development, the "Compatibility" package got renamed to "Support" package when it went from R3 to R4: http://developer.android.com/sdk/compatibility-library.html The AUR has both an 'android-compatibility-package' : https://aur.archlinux.org/packages.php?ID=52967 and an 'android-support-package' : https://aur.archlinux.org/packages.php?ID=53266 The 'android-compatibility-package' is R03, which is the last version with that name. And is, in fact, flagged as out of date. The 'android-support-package' is, in fact, r4, as it should be. And both are maintained by the same person. Should the compatibility package deleted? -- Jonathan Arnold Webstream: http://hieronymus.soup.io Talent wins games, but team work and intelligence wins championships. Michael Jordan
