@vrsmd One of the important dependencies would always fail to compile. net-libs/nghttp2

This was the output of
/var/tmp/portage/net-libs/nghttp2-1.33.0/temp/build.log :
https://0x0.st/ze6k.log

This was the output of
emerge --info '=net-libs/nghttp2-1.33.0::gentoo' :

@MOTT First, I recommend using NVM at the user level to install and manage nodejs versions. https://github.com/nvm-sh/nvm

Second, I've also had issues with programs that use the Boost C++ library. A tactic I often use in this situation is masking the latest version and seeing if the previous version will compile. If it does, I just leave the other version masked and let it upgrade on it's own when an even newer version comes out and see what happens.

@vrsmd NVM looks pretty good. That sounds like it would work pretty well.

Okay. I will keep that in mind

Just remember that I do not use Gentoo at the moment, and it will likely be a little while before I do so again.
