autogen.sh from bzr failed : configure.ac:382: error: expected source file, required through AC_LIBSOURCES, not found

[Daniel Kahn Gillmor]

hi grub folk--

I'm trying to build grub from the current bzr head on a powerpc64 debian
unstable system.  I'm afraid i'm getting stuck right at the beginning,
as i try to autogen:

0 address@hidden:~/src/grub/grub$ ./autogen.sh

I don't know what this error means; i've got gnulib and the various
auto* packages installed:

i've also tried it with automake 1:1.11.6-1 and autogen 1:5.12-0.1, and
i get the same error messages when doing ./autogen.sh from a clean copy.

what am i missing?
