Autoconf bugs?

[Geoffrey Romer <gromer@hmc.edu>]

I'm trying to build a software package from CVS, and I'm getting the following
errors when I try to run autoconf:

---snip---
autoconf: Undefined macros:
***BUG in Autoconf--please report*** AC_LANG_PUSH
***BUG in Autoconf--please report*** AC_LANG_POP

I'm running sid (updated daily), with nothing really fancy that I can think
of. Does this look familiar to anyone, or should I talk to the package
authors?
