Earlier quoted context omitted.
Gentoo is probably the most user hostile Linux distribution I can think of other than ones purposely austere for learning (LFS) or parody (Suicide Linux). If Mac Ports requires that level of knowledge to be user friendly it’s no surprise they lost.
If Gentoo makes your particular computer goal easier to achieve, I don't think it's "hostile". Most people will never need Gentoo or want to use it, but for those with either a need or a desire for a meta-distribution, Gentoo does a pretty good job. I don't think calling it "user hostile" is quite right. I think it's been partially supplanted by other package managers now like Nix/NixOS and even (IMO) XBPS/Void, but…
By any other metric, I would consider it more user-friendly than average. For example, I was very favorably impressed when (not knowing what I was doing), I gave the command to uninstall libc, and after confirming that I really wanted to do that, I was allowed to.
