Building on the Hurd

[Evans Winner]

Does anybody here know anything about building Emacs on the GNU/Hurd/
Mach platform?  I am trying to get a Debian Hurd system up and
running, which, I am aware, is experimental.  apt-get won't let me
install any flavor of Emacs because of dependency problems, so I tried
building from cvs and the compile failed with an error.  I tried
building the 22.1 release tarball and got the same error.  I posted a
note about it to emacs-pretest-bug, for whatever that might be worth.

Are there, possibly, libraries I need that I don't have, or maybe
options I need to pass to configure?  Configure runs without any
problems, so I'm not sure how to proceed.  I will post the last few
lines of make output in case anyone recongnizes something.

What is FFDLY, anyway?

Thanks for any leads.
