error installing numpy on Mac OS X 10.6

I am having lots of trouble installing numpy on Mac OS X 10.6. When I try to install it from source, I get the following error:

I already installed Xcode since I have gcc (version i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1) so it seems unlikely that these header files don't exist. Any idea what might be happening?

thanks.

I installed the EPD packaged python with all the scientific packages on OS X 10.6 based on these two pages: http://cse.ucdavis.edu/~chaos/courses/nlp/Software/PythonOSXInstall.html http://www.soton.ac.uk/~fangohr/computing/pythonsoft.html

Hopefully it is useful.

There is a version (albeit a little bit outdated) of numpy already included on Mac OS X 10.6 in the default Python 2.6 installation. However, if you want a newer version of numpy or would like numpy+scipy, then I suggest you read my installation instructions: Python2.6+NumPy+SciPy+MatPlotLib on Mac OS X 10.6.

Edit
As to the error messages that you are getting.... note that it says "10.4"; numpy has the Mac OS X 10.4 SDK hard-coded into it for some reason, so if you have not installed the 10.4 SDK (which is optional and not installed by default), then you will get these errors. If you reinstall Xcode, and select the Mac OS X 10.4 SDK, so that it is installed, then that should fix the issues that you are getting. That said, I would strongly recommend installing Python.org's MacPython 2.6 and the binary version of numpy.
