Thank you very much for making the stfio library available; it has been very useful and working great so far. Recently, I started getting the error below when importing it. I think this occurred after a macports upgrade. I am sure I have something configured wrong with macports or python. If you could help me figure it out, I would really appreciate it. I'm using OSX Yosemite and Python 3.4.

Thank you,

Sorry for the late reply - for some reason the group posts weren't forwarded to my email.

At any rate could you please try the following:

sudo port selfupdate
sudo port upgrade -u outdated

There was a problem in one of the dependencies that has been fixed in the meantime.
