I tried

but got

This is a bit odd.
Can you please post the output of which libtool

[bwanaaa]

(base) %which libtool
/usr/local/bin/libtool
(base) %

[freesig]

You could try this nodejs/node#2341 (comment)
Looks like it might be an old homebrew version of libtool

[freesig]

Let me know if that doesn't work and we can try to dig into this a bit more

[mitchmindtree]

@dimitre it looks like you might be running into a different error:

couldn't find required command: "cmake"

Unfortunately cmake is required the first time shaderc is built. shaderc is necessary in order to compile GLSL to SPIR-V (the low level shader language representation used by Vulkan). Make sure to check the "All Platforms" and "macOS" sections of the platform-specific setup chapter of the guide.

[kdamball]

You might need to do brew install cmake before running the example draw.
