Have you ever pondered why our software projects have README to explain how to install them?
That's because it can be hard to automate the installation of the dependencies of a project.

In this work, we will challenge and explore the actual difficulty behind why do we still need READMEs and human instructions to install native dependencies for projects, via a research project, called BuildXYZ, which provides an automatic on-demand dependency dispenser based on a FUSE filesystem that will lazily provide the dependency whenever you actually ask for it on the filesystem.

We will show how such a system performs on tasks such as pip install numpy and relate this to the increasing coupling between application-specific package managers and cross-language dependencies, such as Python library with Rust code, e.g. cryptography.
