could not use setup.py to install pyraf using the macports installation of python 2.7

[SmritiM84]

I have installed python 2.7 using macports and it seemed to work fine untill I had to install Pyraf. Amongst others the last bit of the installation code read:

   warning: manifest_maker: standard file '-c' not found
    
    
    The C compiler used to compile Python gcc-4.2, and
    which is normally used to compile C extensions, is not
    available. You can explicitly specify which compiler to
    use by setting the CC environment variable, for example:
    
        CC=gcc python setup.py <command>
    
    or if you are using MacOS X, you can try:
    
        CC=clang python setup.py <command>
    
    
    ----------------------------------------
    Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/zt/rfcx53ks5b7_1_773_2jwpp80000gn/T/pip-build-ImCNyh/astropy

Now I do have gcc installed, so I tried looking for setup.py and I think the one installed with Macports version of Python on my laptop is in /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/python/py-entrypoints/files/

but when I try running python /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/python/py-entrypoints/files/setup.py install

I get

running install
running build
running build_py
creating build
error: could not create 'build': Permission denied

Not sure how to use setup.py to install Pyraf or for that matter other modules. I am using Python 2.7 on Mac OS X 10.9.5

The message stating that Python was compiled with gcc-4.2 is strange. That would not be the case on OS X 10.9.5. OS X 10.6.8 was the last OS X version to feature gcc-4.2. Are you sure you are running MacPorts python? What version of Xcode do you have installed?

Don't try to directly run files inside the MacPorts ports tree; they're not for you; they're for MacPorts to use when installing ports. Each Python module or project will typically include its own setup.py file tailored to that project's needs; that's the setup.py you'll be using to build that project.

Don't forget to use WikiFormatting when writing in Trac.
