Figured out what was wrong with my implementation of Emmanuel Bourg's #kotlin #bootstrap chain (github.com/ebourg/kotlin-boots…), so now I managed to mirror the same chain, but *completely bootstrapped* (all prebuilt jars are removed from sources).
So I have a kotlin from June 2015: framagit.org/tyreunom/guix-and…
still a long way to go :D
