I forgot to mention at the time:  Testing on systems *where time_t is only 32 bits wide by default* is especially useful.

The procedure you used should have worked, assuming $PATH did not change from step to step.  One possible explanation is that there's a bug with building in the source directory -- at step 2, try instead

mkdir _build
cd _build
../configure

Another possible explanation is that the bootstrap operation didn't set file timestamps accurately (perhaps because the filesystem you're on doesn't support high-resolution time stamps) and so it's trying to regenerate 'configure' with an _older_ autoconf which trips over some state left by the bootstrap process.  Another thing to try is

./bootstrap
sleep 2 && touch aclocal.m4 && sleep 2 && touch Makefile.in && sleep 2 && touch configure
./configure
sleep 2 && touch config.status && sleep 2 && touch tests/aclocal Makefile lib/version.m4
make

Please let us know if either of those things helps.
