Returning to that Mac OS X box to try it, I again went with the
defaults.

    $ sh build_nmh
    Install prefix [/usr/local/nmh]: 
    Locking type (dot|fcntl|flock|lockf) [determined by configure]: 
    MTS (smtp|sendmail/smtp|sendmail/pipe) [smtp]: 
    SMTP server(s), space separated [localhost]: 
    Cyrus SASL support [determined by configure]: 
    TLS support [determined by configure]: 
    build succeeded, build log is in nmh/build_nmh.log
    $ 

The last two could do with something indicating what the answers can be
if the default isn't wanted.

Selected log highlights.

An `rm *' in a clean-up is finding a directory has been produced!?

It's clang, based on the later error messages.  A `cc -v' says
