[PyMOL] Problem With Dynamic_Gromacs Plugin

[Stephen P. M. <s.m...@sb...>]

I just downloaded, compiled and installed gromacs-2020 without any 
warnings or errors.  However when I attempt opening the Dynamic_Gromacs 
2.2.1 plugin I get the error:

'module' object has no attribute 'showerror' and everything stops.

Now, the plugin has been working with the Debian Stretch default 
gromacs-2019.1. Further, with the gromacs 2020 installation gmx command 
executes correctly at the command line.

I may be wrong, but, might this be a PyMOL  error?

Thanks in advance.
