I was using Debian Squeeze with GNU make 3.81. I executed `make 
maintainer-clean' at the root and then `./configure' and `make 
bootstrap' when it failed.

I am not sure what version of gnulib my Makefile was based on.

I am not sure how to determine if this was the case, since running 
./autogen.sh, ./configure and make bootstrap fixed the problem.

Let me know if I can help to further troubleshoot this.
