Problems compiling C core of igraph with Python 2.7.9 Anaconda 2.2.0 on Mac osx 10.10.2

Question

I wonder if anyone has had a similar issue to this and found a solution? I am trying to install igraph for with Python 2.7.9 Anaconda 2.2.0 on Mac osx 10.10.2.

I managed to brew install homebrew/science/igraph OK but when I try to pip install python-igraph I get the following error:

   grep: /usr/lib/libiconv.la: No such file or directory
        sed: /usr/lib/libiconv.la: No such file or directory
        libtool: link: `/usr/lib/libiconv.la' is not a valid libtool archive
        make[3]: *** [libigraph.la] Error 1
        make[2]: *** [all] Error 2
        make[1]: *** [all-recursive] Error 1
        make: *** [all] Error 2

    Extracting igraph-0.7.1.tar.gz...
    Configuring igraph...
    Could not download and compile the C core of igraph.

I have tried sudo pip too with the same results. Any suggestion on what to try next would be much appreciated

Found a solution, I had to brew install pkg-config first, hope this helps anyone else with the same error
