Fair enough but a ports or portage recipe with use flags that are known to work are more likely to produce the expected results and do so for everyone rather one for the few custom builders who do it right. My concern is based on the fact that I see rebuilding nginx as part of getting started guides for many things, including rtmp streaming and since these guides are usually followed by less knowledgeable nginx users who say just want to stream, the numbers of broken or vulnerable nginx setups increases substantially. How many of those setups would be up to date if they were installed via a ports tree compared to the current manual configure and make steps and need to follow nginx upstream for new releases. In pkgsrc, gentoo, nix, etc. others already took care of that and you just have to run e.g. emerge.
