matplotlib is should already be attempting to dynamically link libz when
it generates ft2font.so. I wonder why it wasn't for you. Can you
revert any manual changes, remove the build directory ("build" at the
top of the source tree), rebuild ("python setup.py build") and attach
the output to this list?
