I thought it was an optional dependency because when I run
`./configure --help', it contains the following help:

  --with-openssl          use libcrypto hash routines. Valid ARGs are: 'yes',
                          'no', 'auto' => use if available, 'optional' => use
                          if available and warn if not available; default is

Perhaps someone unaware of the issue adds this? Should I open a bug
report on this?

Indeed, the Debian package does not depend on openssl.
