I get the same problem but with Plone 5.0.8 using the training module https://training.plone.org/5/theming/theme-package.html
(buildoutvenv)root@www:/opt/plone5/ploneconf.theme# ./bin/buildout

Installing instance.
An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

I can only interrupt with Ctrl-C because here is an endless loop.
