Yep. If you just run configure with no arguments you get
man page install path      : ${prefix}/share/man

The trouble is that there are several layers of indirection
to be undone:
mandir is    ${datarootdir}/man
nmhman is    ${prefix}/share/man
nmhman2 is   /usr/local/nmh/share/man

(The reason autoconf leaves these unexpanded is so you can
specify a different prefix when running make and have all
the dependent variables adjust correctly without having to
reconfigure.)

Anyway, I guess autoconf must have changed at some point so
the default value of mandir needs an extra level of expansion.

I couldn't see a clean good way to expand only the
right number of times here, so I've just committed a
slightly tweaked version of markus' patch.

If anybody has a better suggestion we can do that instead :-)
