[igraph] Unable to install python-igraph on Linux Mint 12

[Colin Morris]

I've been unable to install python-igraph. Here's what I've tried:

1) Adding the igraph PPA (https://launchpad.net/~igraph/+archive/ppa), to my sources.list, running apt-get update, and then apt-get install python-igraph. This gives this error message:

The following packages have unmet dependencies:

 python-igraph : Depends: python (< 2.7) but 2.7.2-7ubuntu2 is to be installed

E: Unable to correct problems, you have held broken packages.

Some googling suggests that this is a longstanding issue (see this post from 2010: http://lists.gnu.org/archive/html/igraph-help/2010-10/msg00070.html)

2) `easy_install python-igraph` gives a message about a missing header file:

src/random.c:27:27: fatal error: igraph_random.h: No such file or directory compilation terminated.

Which I learned is because I need to install the C library before installing the bindings. So I downloaded the C source code here (http://sourceforge.net/projects/igraph/files/C%20library/0.6.5/igraph-0.6.5.tar.gz/download) and followed the installation instructions (./configure; make; make install) which went okay.

Then I reran easy_install, which seemed to be successful. Then when I try to import igraph in python, I get:

>>> from igraph import Graph

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/usr/local/lib/python2.7/dist-packages/python_igraph-0.6.5-py2.7-linux-x86_64.egg/igraph/__init__.py", line 34, in <module>

    from igraph._igraph import *

ImportError: /usr/local/lib/python2.7/dist-packages/python_igraph-0.6.5-py2.7-linux-x86_64.egg/igraph/_igraph.so: undefined symbol: igraph_warning_handler_ignore

>>> 

3) I uninstalled the version of igraph I got from easy_install using `pip uninstall python-igraph`. Then I downloaded the source from http://pypi.python.org/packages/source/p/python-igraph/python-igraph-0.6.5.tar.gz and ran `python setup.py install`.  Same error message as above when trying to use igraph.

And yeah, I'm pretty much ready to admit defeat. Any tips?
