@blainesch It's possible that you have a new enough version of autoconf, but an older version of autom4te. Could you check autom4te --version?

[georgebrock]

I've just set up Travis CI for this project. Travis' build workers have autoconf 2.68 installed, so I had to drop the required version (but I'm happy to do so, since the configure script will be run as part of the tests).

This might help to resolve this issue.

Here's how I got around it.

bundle
AUTOM4TE=/usr/local/bin/autom4te ./autogen.sh
RUBY=/Users/blaineschmeisser/.rvm/wrappers/ruby-2.0.0-p195/ruby ./configure
# was trying to use system ruby 1.8.7
make
rspec

Can this be closed?

[georgebrock]

Since this only affects developers, and there have been no other reports of it for the last 3 months, I think we can close it.
