I've implesmentd a new version of buld_ext.py and created a version of core.py and extension.py.

first thing I noticed when running a patched Cython: setuptools break. They already patch into distutils, so the patching in your code doesn't work. I would prefer doing without changes to core.py and extensions.py. AFAICT, this removes the support for configuring import directories at the Extension level. Alternatively, we could also import things from setuptools first and only fall back to distutils. However, this would bug people who have setuptools installed and want to build with distutils (for whatever reason, don't know how common that is). I'll take a deeper look into this. Stefan

Stefan,

I've looked at the setuptools source.  Since setuptools is importing Pyrex.Distutils to perform work, setuptools will have to be patched to work with the new code.  From my initial walkthrough of the code (by no meas through), it appeas that the only change would be to change occurances of 'distutils.core' to 'Pyrex.Distutils.core', wrapped in a try ... except statement.  For example:

try:
    from Pyrex.Distutils.core import Extension
except ImportError:
    from distutils.core import Extension
-- or --
try:
    import Pyrex.Distutils.core
except ImportError:
    import distutils.core

The files that would have to change are:

command/upload.py
command/easy_install.py
dist.py
extension.py
__init__.py
package_index.py
tests/__init__.py

Extension is always importted from core, so with the change stated above it will always get the correct Extension class.
build_ext is already imported from Pyrex.Distutils.
