emerge does anyway.

I would not really like to do this, since this installs files beside the
portage system and I'm not a friend of this. (Long time ago I had a
slackware-install and installed other programs "from source" beside it.
Since there was chaos at the end, I'm a little shy concerning these
things.)

I'd suggest tuning make.conf the following way:

1) Add FEATURES="nostrip"
2) Use CFLAGS="-ggdb3 -O1"

The call for configure in the ebuild uses the default options 
                --sysconfdir=/etc/leafnode \
                --with-runas-user=news \
                --localstatedir=/var \
                --with-spooldir=/var/spool/news \
                $(use_with ipv6) \
                $(use_with pam) 

Probably there's no harm in any of these. So a "emerge leafnode" could
be fine after that, couldn't it?

In case he provides the time between the last fetchnews working and the
first time not working I could do some research. "find" in the
portage-tree should be alright.

Anybody out there who's willing to write a working nightly-ebuild? ;-)
