New version of Anaconda, missing modules

Hi guys! I’m trying to use heborist to configure de Dynamixel motors, in the documentation of heborist it says heborist needs PyQt4 and this documentation suggests use Anaconda; morover, the latest versions of Anaconda work with PyQt5 instead of PyQt4.
I want to know how I can install PyQt4 or where I can find an older Anaconda version wichi supports PyQt4.

Thanks everyone

indeed, moreover Bootle and Pyserial aren’t install with the latest version of Anaconda.
You can install this modules with this command: ‘pip install <module_name>’ in a terminal.

We try to find a better alternative.

Thanks so much I will try with Anaconda.
