The err about python interface

[ghost]

I installed Shogun on the ubuntu16.04 through the python interface，
When I execute: cmake -DPythonModular=ON ..
The following error occurred:

@xxnyufengzhe Hi, thank you for your report this. So, from the error message, I believe you missing some necessary package for shogun compiling, etc Ctags. Try to install Ctags and try it again? :)

I cite the error message:
