ImportError: /usr/local/lib/libair_modes.so.0: undefined symbol: _ZN2gr5block...

This error occurs after a successful install and an attempt to run modes_rx. I have read a previous and similar error and tried to follow some of it's steps, such as reinstalling GNU Radio. Here is that thread.

Here is the traceback:

Traceback (most recent call last):
  File "/usr/local/bin/modes_rx", line 27, in <module>
    import air_modes
  File "/usr/local/lib/python2.7/dist-packages/air_modes/__init__.py", line 50, in <module>
    from air_modes_swig import *

ImportError: /usr/local/lib/libair_modes.so.0: undefined symbol: _ZN2gr5blockC2ERKSsN5boost10shared_ptrINS_12io_signatureEEES6_

When I check ldconfig:

$ sudo ldconfig -p | grep air_modes
    libair_modes.so.0 (libc6,x86-64) => /usr/local/lib/libair_modes.so.0
    libair_modes.so (libc6,x86-64) => /usr/local/lib/libair_modes.so

Also, this may be of help:
