Hi all,

Very new to VMD and I have been trying to install DruGui, following the instructions on DruGui site. However, VMD is not installing the plugin and giving me the following error:

Info) -------------------------------------------------------------
Info) Multithreading available, 4 CPUs detected.
Info) OpenGL renderer: Intel(R) Iris(TM) Graphics 6100
Info) Full GLSL rendering mode is available.
Info) Textures: 2-D (16384x16384), 3-D (2048x2048x2048), Multitexture (8)
Info) Dynamically loaded 2 plugins in directory:
Info) /Users/smturzo/Desktop/dev/vmd/VMD
The drugui package could not be loaded:


Additional information:

Python version: Python 2.7.14

Numpy version: 1.12.1

I have also added the plugin installation line in loadplugins.tcl in line 186 as shown here:
