As indicated in your stackoverflow.com reference, this is not a problem with libvisio per se but a problem with boost
when using libstdc++ (default c++ lib on Mac OS X earlier than 10.9). This builds correctly on 10.9+ where libc++ is
Now that trac is back up, suggest you file a ticket against boost including the information included in this message and
attach your log file there as well. Don't forget to CC the boost maintainer. He will probably want to file a bug
report upstream with the boost developers.
port info --maintainer boost
CCing the boost maintainer now for his info.
