What does which python return for you? By the version number it looks like you're using the system one. If that's the case, you might want to try doing sudo port select python python27 so that MacPorts's python27 is your default python.

I ran the commands and the output is below. I'm now using MacPort's Python27 but unfortunately I still encounter the same error when attempting the import.

$ which python
/usr/bin/python

$ sudo port select python python27
Selecting 'python27' for 'python' succeeded. 'python27' is now active.

$ which python
/opt/local/bin/python
