+Known build errors
+------------------
+
+If Cython compilation fails with the error ``cpython.pycapsule.pxd not
+found`` (for Cython 0.14), try to `install Cython 0.15
+<http://www.cython.org/#download>`_ instead. 
+
+On Windows, the error ``Error:unable to find vcvarsall.bat`` means that
+distutils is not correctly configured to use the C compiler. Edit (create
+if not existing) the configuration file ``distutils.cfg`` (located for
+example at ``C:\Python26\Lib\distutils\distutils.cfg``) to be::

+    [build]
