Curious about situations or repos that have given you the most painful setups or dependency hell!

Could be something repo-specific (weird build systems, architecture-dependent steps, broken/missing docs), or something caused by your own machine quirks (multiple Python env managers, conflicting toolchains, GPU/CUDA messes, etc.).

Would love to hear concrete examples — what your local setup looked like, what the repo expected, and where things went sideways.

Thanks y’all!
