[igraph] Installing igraph to use on FreeCAD

[Floriane B]

Dear All, 

I got a problem while trying to install igraph to use on python27, implemented in FreeCAD. 

I tried to install it with MacPorts. 

Here are my computer settings: 

Logiciel  OS X 10.9.5 (13F34)

Here is the error I face while trying to install igraph: 

Error: org.macports.activate for port python27 returned: Image error: /Applications/MacPorts/Python 2.7/IDLE.app/Contents/Info.plist already exists and does not belong to a registered port.  Unable to activate port python27. Use 'port -f activate python27' to force the activation.

Error: Failed to install python27

Please see the log file for port python27 for details:

    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_python27/python27/main.log

Error: The following dependencies were not installed: py27-setuptools python27

To report a bug, follow the instructions in the guide:

    http://guide.macports.org/#project.tickets

Error: Processing of port py27-igraph failed

Do you think i should force the activation of port python27 ?

Thank you very much in advance !!
