Comment 5 for bug 68163

Actually this proves only that crypto is broken at debian unstable too. Though in some different way.

If it were working you'd see this:

zeank@sz2:~$ erl
Erlang (BEAM) emulator version 5.4.9 [source] [threads:0]

Eshell V5.4.9 (abort with ^G)
1> crypto:start().
ok
2>

If you get

{undef,[{crypto,start,[]},{erl_eval,do_apply,5},{shell,exprs,6},{shell,eval_loop,3}]}

instead, this means that a matching call 'start' within module 'crypto' could not be found.
