As stated emerging app-portage/gentoolkit-dev, the gensync utility has been deprecated in favor of app-portage/layman. Thus eix-sync should use layman to sync overlays instead of gensync.
Created attachment 120060 [details, diff] eix-0.9.6-layman.patch It patches eix-sync.in and eix.1.in to refere layman instead of gensync. eix-sync option '-g' is renamed to '-l' to keep it mnemonic: -g was to skip gensync, -l is to skip layman.
Thanks for the patch. I added it unchanged to eix svn trunk.
fixed with 0.9.7, thank you!
