Importing matplotlib in Spyder (OSX 10.6)

When importing matplotlib in Spyder I get the following: 

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Applications/Spyder-Py2.app/Contents/Resources/lib/python2.7/matplotlib/pyplot.py", line 27, in <module>

    import matplotlib.font_manager as font_manager

    from matplotlib import ft2font
ImportError: dlopen(/Applications/Spyder-Py2.app/Contents/Resources/lib/python2.7/matplotlib/ft2font.so, 2): Symbol not found: _inflateReset2
  Referenced from: /Applications/Spyder-Py2.app/Contents/MacOS/../Frameworks/libpng16.16.dylib
  Expected in: /usr/lib/libz.1.dylib
 in /Applications/Spyder-Py2.app/Contents/MacOS/../Frameworks/libpng16.16.dylib

What can I do? I really don't get it. I run under mac OSX 10.6

(Spyder dev here) The problem lies in some changes done by the Matplotlib team some time ago that made for us harder to support Mac OSX 10.6.

To do it, we would need to include our own version of zlib in our Mac app, and compile every package against it, something I considered too much work and a potential cause of bugs.

That's why I changed the minimal required version of our app to be 10.7, as can be seen in our documentation site.
