Upgraded from python 2.5.5 to 2.6.6 and it works fine now.
Shouldn't the python version be checked when Sphinx is called.

This can happen if you build your Python before installing the zlib development headers.

(The zlib packages only contain the library, not the Python module.)

In any case, this is not a Sphinx issue.
