Created attachment 581578 [details] Fixed ebuild using eautoreconf The libtool shipped with dev-python/notify-python is too old to understand `-flto` in CFLAGS. A detailed link can be found here on the Gentoo Wiki: https://wiki.gentoo.org/wiki/Outdated_libtool The fix is to force autoreconf in the src_prepare stage. A fixed ebuild is attached.
