I've seen this before. Either you have an old version of ant, or your
JAVA_HOME is not set, or it's set incorrectly (to 1.5 and ant is built
for 1.6, or vice versa).

Hi Steven -
I also see that problem if I build on my Mac sometimes. I'm looking into a
proper fix, but for now you can do:
ant compile
sudo python src/python/setup.py install
to build and install manually. If you have a moment, can you let me know
which ant you are using? (ant -version)
Thanks for bringing this up!

Any idea how I can get it to build? ZooKeeper 3.2.1 (tarball release) on
