Description    :
Emscripten is a toolchain for compiling to asm.js and WebAssembly, built using
LLVM, that lets you run C and C++ on the web at near-native speed without
plugins.

I try to make new nodejs facility to compile all JS stuff into one ELF binary that contains node + the app.

I have checked out the following:

radziecki> git log -1 --oneline
3c4f208 (HEAD -> main, tag: v1.0.0-alpha.6, origin/main, origin/HEAD) release: 1.0.0-alpha.6
radziecki> git remote -v
origin	https://github.com/nodejs/postject (fetch)
origin	https://github.com/nodejs/postject (push)

and using www/node20 and yarn to build it with "yarn build" I end up with the following during the final linking stage:

Shall the additional component be installed with the port?

I can see there are
