Import error: undefined symbol

[oliviaylee]

Hi,
I installed tracikpy following the instructions on the ReadMe, however I'm running into this issue:

>>> import numpy as np
>>> from tracikpy import TracIKSolver
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File ".../tracikpy/tracikpy/__init__.py", line 1, in <module>
    from .trac_ik_solver import TracIKSolver
  File ".../tracikpy/tracikpy/trac_ik_solver.py", line 9, in <module>
    from .swig.trac_ik_wrap import TRAC_IK
  File ".../tracikpy/tracikpy/swig/trac_ik_wrap.py", line 10, in <module>
    from . import _trac_ik_wrap
ImportError: /lib/x86_64-linux-gnu/libkdl_parser.so.1d: undefined symbol: _ZN4urdf5Model7initXmlEPKN8tinyxml211XMLDocumentE
>>> 

I was wondering how I can get around this? Thank you.
