The symbolic link seems to have indeed solved the problem (though I also had to do it for "libicuuc.so.56" and "libicudata.so.56"). Thank you for the suggestion! I agree Tiago, this does not seem to be a problem caused in graph-tool itself but anaconda comes with a lot of packages and thus a lot of possible mailing lists so I was wondering how to tell which package was being called when the issue arose so that I can go away and talk to the right people about finding a fix/workaround. It seems like we have a workaround now though. -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
