From https://en.wikipedia.org/wiki/Scheme_(programming_language):
"Scheme has a diverse user base due to its compactness and elegance, but its minimalist philosophy has also caused wide divergence between practical implementations, so much that the Scheme Steering Committee calls it "the world's most unportable programming language" and "a family of dialects" rather than a single language."
Any programming language is only as compact and elegant as its installation procedure on different computers and operating systems.
