running a python script that requires matplotlib gives: ImportError: undefined symbol: __libm_sse2_sincos

Question

A specific package that I'm trying to run is fastStructure. After installing all the requirements (numpy, scipy, cython, gsl, matplotlib), when I try to execute the script I get the following error:

python distruct.py
Traceback (most recent call last):
  File "distruct.py", line 2, in <module>
    import matplotlib.pyplot as plot
  File "/data003/GIF/software/packages/python/2.7.9/lib/python2.7/site-packages/matplotlib/pyplot.py", line 24, in <module>
    import matplotlib.colorbar

ImportError: /data003/GIF/software/packages/python/2.7.9/lib/python2.7/site-packages/matplotlib/_path.so: undefined symbol: __libm_sse2_sincos

Does this mean that some of the requirements weren't properly installed? or Am I missing some of the basic packages that are supposed to be there on all computers? If it helps I am on a large HPC cluster, running RHEL with intel processors. I am unable to find any information about this error and I am unable to move forward. Any help will be greatly appreciated.

EDIT:

Specifically,

   import matplotlib.pyplot as plot

is what causing this error.
