Fails to check dependencies on python-gtk2

On a fresh install of ubuntu 16.04, ./MAGICK-INSTALL fails with this console message:

Traceback (most recent call last):
  File "./MAGICK-INSTALL", line 10, in <module>
    from gui_gtk import *
  File "/home/karlrt/Downloads/magick-rotation-1.6.2/gui_gtk.py", line 3, in <module>
    import gtk
ImportError: No module named gtk

EXPECTED OUTOME
it should check for the mission module and advise user to install it, or install the dependency on its own

FIX
sudo apt-get install python-gtk solves the issue
