ERROR: end of file in string

[Benjamin Reed]

I'm trying to do an autoreconf in the gnome-doc source, and I'm
getting this error:

---(snip!)---
NONE:0: /pangocairo/bin/gm4: ERROR: end of file in string
autom4te: /pangocairo/bin/gm4 failed with exit status: 1
---(snip!)---

I know this works for some large combination of autotools and libtool
because it has only recently broken in fink, and gnome-doc hasn't
changed for some time.

How do I go about debugging what's actually going wrong?  The docs say
it's a dangling quote, but everything seems quoted right in
configure.in, and everything else comes from other projects' files
which have (presumably) worked in the past.

even running the failing autom4te command in "trace" mode isn't very
enlightening:
