The following packages in the enlightenment overlay have been moved to the subdirectory "IN-EFL": dev-libs/eina dev-libs/eet dev-libs/embryo media-libs/evas dev-libs/eobj Adding ESVN_SUB_PROJECT="IN-EFL" fixes the download path in those ebuilds. The exception is dev-libs/eobj which has been renamed to "eo" in addition to the move. If the package is renamed to dev-libs/eo, the depends in media-libs/evas and media-libs/edje need to be adjusted. To verify, here the corresponding link to the enlightenment svn repository. http://svn.enlightenment.org/svn/e/trunk/IN-EFL/
Upstream broke some live ebuilds and will break more of them during the move to a merged efl tree. Since the changes have not settled yet, dont expect updated ebuilds anytime soon. For your suggestion: Using the IN-EFL subdirectory is a bad idea, since that target does not get any updates, only the sources in efl/src/* are maintained. In the meantime, just go with the released versions of the libraries and e17.
packages have been moved to git and eclass+basic ebuilds used by e17 have been adjusted, so closing this as fixed. If there are further packages needing a migration, please open a seperate bug for them.
