[erlang-questions] bcrypt issue -- missing library?

Hello,
 
I've been using [ https://github.com/ferd/erlpass ]( https://github.com/ferd/erlpass ) successfully in my code for several years.
 
But I recently had to recompile my system. When I then tried to run the sign-in function, which had never before given me problems, I got this error message:
 
(wgd@REDACTED)2> show_page: "sign-in"
=INFO REPORT==== 28-Mar-2018::14:04:16 ===
{error,postback_request,
 {url,"localhost:8020/wg_members/sign-in"},
 {exit,
 {noproc,
 {gen_server,call,
 [bcrypt_nif_worker,
 {hashpw,<<"lloyd">>,
 "$2a$12$Hnn1TK6HyTds7Xmf326k1.OIh/OEwi9uWqHNjHVwEQw0NKVw6X5LO"},
 
I then checked to see if crypto was started and it was:
 
(wgd@REDACTED)2> application:start(crypto).
{error,{already_started,crypto}}
 
But application:start(bcrypt) turned up this error message:
 
(wgd@REDACTED)4> application:start(bcrypt).
=WARNING REPORT==== 28-Mar-2018::14:12:39 ===
The on_load function for module bcrypt_nif returned {error,
 {bad_lib,
 "Library version (2.11) not compatible (with 2.8)."}}
{error,
 {{shutdown,
 {failed_to_start_child,bcrypt_nif_worker,
 {undef,
 [{bcrypt_nif,create_ctx,[],[]},
 {bcrypt_nif_worker,init,1,
 [{file,"src/bcrypt_nif_worker.erl"},{line,31}]}
 
So now I'm stuck.
 
I'm running Erlang/OTP R19
 
Can anyone tell me how to get bcrypt or functional equivalent working again?
 
All the best,
 
LRP
