Cython & Hadoopy compiling error.. any ideas on a fix?

I'm trying to run Hadoopy, but am getting a compiling error on OS X:

ImportError: Building module failed: ["CompileError: command 'llvm-gcc-4.2' failed with exit status 1\n"

I have /Developer/usr/bin in my $PATH, and am running latest version of XCode on OS X Lion 10.7. Cython was installed via easy_install.

Full output:

For me it was an installation issue and i had fixed it sometime back using below mentioned steps:

• pip install argparse

• git clone https://github.com/bwhite/hadoopy.git

• cd hadoopy

• python setup.py install

Instead of using pyximport, build the extension modules in place with python setup.py build_ext --inplace (or install for in-place development with python setup.py develop, or just a regular install via python setup.py install). For packages you almost always want to run the setup, which will properly configure the compilation environment, build, and installation process.

pyximport is good for your personal scripts if you're using Cython to speed up your code (e.g. for scientific computing). Even then you might need to bring in other libraries, and build from multiple sources. In that case, you can use a pyxbld file to set up the sources and include_dirs. For example, say you have foo.pyx, then you can place build instructions in a foo.pyxbld in the same directory. For example:

#foo.pyxbld
def make_ext(modname, pyxfilename):
    from distutils.extension import Extension
    return Extension(name = modname,
                     sources=[pyxfilename, 'bar.c'],
                     include_dirs=['/myinclude'] )
def make_setup_args():
    return dict(script_args=["--compiler=mingw32"])

Now using foo is as simple as the following:

import pyximport
pyximport.install()
import foo

Presuming there's no compilation errors, it's virtually transparent but for the delay the first time you import the module. Subsequent imports will look for the built extension in the .pyxbld subdirectory of your home/profile directory.
