pyfftw and fftw3 in Python 2.7, Ubuntu 16.04

Hi!

I have been trying to run FFTW (3.3.4) alongside pyfftw (0.10.1) in Spyder (2.3.9), python version : 2.7.11, Ubuntu 16.04. Cython (0.23) is set without any problems.

I tried to install both packages manually and through repositories. In all cases, that is the error I get from the console:
File "/usr/lib/python2.7/dist-packages/pyfftw/__init__.py", line 16, in <module>

from .pyfftw import (
ImportError: /usr/lib/python2.7/dist-packages/pyfftw/pyfftw.x86_64-linux-gnu.so: undefined symbol: fftwl_plan_with_nthreads

and when I try importing pyfftw in IPython
ImportError Traceback (most recent call last)
<ipython-input-1-c7c3740380ed> in <module>()
----> 1 import pyfftw

/usr/lib/python2.7/dist-packages/pyfftw/__init__.py in <module>()
14 from .version import version as __version__
15
---> 16 from .pyfftw import (
17 FFTW,
18 export_wisdom,

ImportError: /usr/lib/python2.7/dist-packages/pyfftw/pyfftw.x86_64-linux-gnu.so: undefined symbol: fftwl_plan_with_nthreads

Your recommendations are highly appreciated, thanks in advance!
