Help! Trying to install nmh on ubuntu

Here is the result of sb_release -a:

  Distributor ID:       Ubuntu
  Description:  Ubuntu 18.04.3 LTS
  Release:      18.04
  Codename:     bionic
  No LSB modules are available.


I have given up trying to install nmh from a package, deciding instead
to install from the sources. But

  ./configure  --prefix=/usr/local/nmh-1.7.1ubuntu/

fails.

I will attach config.log.

Thank you, as they say, in advance.
