[NTG-context] How can I make a Gentoo Linux package for ConTeXt LMTX?

[amano.kenji]

TexLive has texmfcnf.lua that doesn't really work with texlive-context installed by linux distributions.

Arch Linux has its own patched version of texmfcnf.lua.

It seems I'd be better off with a linux package for ConTeXt LMTX.

How can I build and install ConTeXt LMTX on Gentoo Linux or any linux distribution?

I wish it was as simple as ./configure, make, and make install.
