Msmtp configuration error


After trying to install and configure msmtp by using this guide ( and its source, I'm getting these error lines at PuTTy:

Error relocating /usr/lib/ explicit_bzero: symbol not found
Error relocating /usr/lib/ getrandom: symbol not found

My msmtprc file is like this:

# Example for a system wide configuration file

# A system wide configuration file is optional.
# If it exists, it usually defines a default account.
# This allows msmtp to be used like /usr/sbin/sendmail.
account default

# The SMTP smarthost

# Use TLS on port 465
port 587
tls on
tls_starttls on
tls_certcheck off

# Construct envelope-from addresses of the form "user@oursite.example"
#auto_from on
#maildomain oursite.example

# Syslog logging with facility LOG_MAIL instead of the default LOG_USER
syslog LOG_MAIL
auth login
password yyyyyyyyyyyyyyy

What are these errors and how to solve this?

Upgrade libnettle to the latest version (3.4.1-1).
