elixir build failure, NetBSD 9 amd64, 2022Q4

[Greg Troxel <gdt%lexort.com@localhost>]

I did build elixir 1.14.0 on November 21 on another box, and on December
28 on the one that's failing.   I suspect erlang was at 23.3.4 then.


The failure is:

  ==> eex (compile)
  warning: the VM is running with native name encoding of latin1 which may cause Elixir to malfunction as it expects utf8. Please ensure your locale is set to UTF-8 (which can be verified by running "locale" in your shell)

  {"init terminating in do_boot",{undef,[{'Elixir.Kernel.CLI',main,[["+elixirc","--ignore-module-conflict","lib/**/*.ex","-o","ebin"]],[]},{init,star
  t_em,1,[]},{init,do_boot,3,[]}]}}
  init terminating in do_boot ({undef,[{Elixir.Kernel.CLI,main,+elixirc--ignore-module-conflictlib/**/*.ex-oebin,[]},{init,start_em,1,[]},{init,do_bo
  ot,3,[]}]})

and I normally have

  LANG=""
  LC_CTYPE="en_US.UTF-8"
  LC_COLLATE="C"
  LC_TIME="C"
  LC_NUMERIC="C"
  LC_MONETARY="C"
  LC_MESSAGES="C"
  LC_ALL=""

I tried C.UTF-8 and setting LC_ALL.

I wonder if I have to rebuild erlang  that way?  Or if erlang or elixir
is just buggy?
