This is actually why I immediately discard use of the system package manager. One library version set per OS installation means that I can't run two things on the same machine unless I get really lucky with dependency versioning. Now the only way to get things done is to spin up one virtual machine per project, and completely setting up a new development environment per project is a huge pain in the ass that can only be optimized so far.

nix/guix is a sort of reasonable answer to this issue, I guess, but then you have to develop on nix/guix and hope that apt/rpm/pacman can handle your dependencies.
