 # Elm 0.19 changed the language & package ecosystem completely,
 # essentially requiring a partial rewrite of all Elm apps. However,
 # //fun/gemma uses Elm 0.18 and I don't have time to rewrite it.
+#
+# Since the ABIs of current glibc and the pinned version have diverged
+# too much, we need to build //fun/gemma completely based on a historical
+# nixpkgs version.
