Hi Tamas, Thanks for your help. I did need upgrade to using the python.org installer (not from source). Is there a way to trick the installer into using this (e.g., what is the installer looking for to see if this is an apple provided python).
I haven't installed igraph before this and don't see older igraph associated C files anywhere on my hard drives added before yesterday. If tried using alternative GCC compilers (4.0 vs. 4.2) and ARCHFLAGS='-arch i386 -arch x86_64' when running setup.py.

Chances are that you have installed Python on your own (either by downloading an installer from python.org, or compiling it yourself). The installers we provide on PyPI work with the version of Python that is bundled with the operating system by Apple. Can you please confirm that you are indeed trying to install igraph into a custom Python installation and not the default one provided by Apple? > #2 ---------------------------- > The C libraries were installed in: /usr/local/Cellar/igraph/0.6/ include/igraph (sym linked from /usr/local/include/).

If the C libraries were installed in /usr/local/Cellar/igraph/0.6/include/igraph, then why does the compiler refer to include files in /opt/local/include/igraph? Do you have any "old", leftover igraph installation on your machine that the compiler could be picking up instead of the include files in /usr/local? If so, please delete the igraph includes from /opt/local/include and any leftover igraph libraries from /opt/local/lib and try again. All the best, Tamas On Thu, Feb 14, 2013 at 8:52 PM, Nathan Salomonis <[email protected]> wrote: > Hi all, > > > > I have been trying hard to get igraph installed for my Mac 10.6.8 in python > 2.7.
