Rant: a minor clue when using autoconf
It's not enough to just dump @foo@ in your Makefile.in and
then just blindly -- untested, in releases! -- expect the
right things to happen. Esp. when @foo@ expands to ${bar},
make sure that you define "bar" in your Makefile also,
e.g.
bar= @bar@
Now guess what - this has to go up ALL THE WAY, until everything
is defined. Who would have thought... *sigh*
