Support for external ell library has been stable for a long while now. We should stop bundling these together in iwd builds patch attached Reproducible: Always Steps to Reproduce: current iwd builds do not use dev-libs/ell but instead build their own static bundled version
Created attachment 884574 [details, diff] iwd-2.13.ebuild patch
I'm a bit confused by the patch-- currently only iwd-9999 actually uses bundled ell, but you're only modifying iwd-2.13.ebuild. I'm not sure what value there is in allowing iwd-9999 to use a (possibly out of sync) system ell copy.
