Just FYI for anybody else building on OSX:

libtool is a new dependency, so if you update to git HEAD and have trouble
building:

brew install libtool
  (or port install libtool -- see doc/build-osx.md for all the dependencies)
./autogen.sh
./configure  .... etc, whatever configure options you use. I develop with:
./configure --disable-hardening --disable-silent-rules CXXFLAGS='-g3 -O0
-DDEBUG_LOCKORDER'
