How, exactly, can I make bzr-svn work on OS X Leopard

OS X Leopard comes with SVN 1.4.4 and Python 2.5 and SVN SWIG for Python 2.5. This won't work for bzr-svn.

I tried the 1.4.x SVN branch w/ patch and the 1.5 trunk SVN branch and compiled it to /usr/local. None of it works for me. I have banged my head against this to the point of bloody and helpless.

# Install Bazaar
sudo easy_install -U paramiko pycrypto bzr

# 1.4 subversion & patch
cd /tmp
rm -rf subversion*
curl -O http://subversion.tigris.org/downloads/subversion-1.4.6.tar.bz2
tar xvfj subversion-1.4.6.tar.bz2
cd subversion-1.4.6
curl http://samba.org/~metze/subversion-1.4.0-metze-python-bindings.patch \
  | patch -p1
./configure \

make
make check
sudo make install
make swig-py

sudo make install-swig-py
cd ..

export LD_LIBRARY_PATH=$HOME/lib:/usr/local/lib
export PYTHONPATH=/usr/local/lib/svn-python

# Check it ---
python -c "import svn.delta; print svn.delta.__file__"

#
# Boink! This rest of this script is broken and doesn't work
#

python -c "from svn.delta import svn_delta_invoke_txdelta_window_handler"
# Errors out and makes the rest of this script pointless

# Install the bzr_svn plugin
# ( http://bazaar-vcs.org/BzrForeignBranches/Subversion )
mkdir ~/.bazaar ~/.bazaar/plugins
cd ~/.bazaar/plugins
rm -rf svn
bzr branch http://people.samba.org/bzr/jelmer/bzr-svn/stable svn

# Try it
bzr branch http://macromates.com/svn/Bundles/trunk/ textmate-bundles
