When trying to install the module on a rakudobrewed 2017.06 it fails as below:

I haven't been able to reproduce this. Both my own testing and Travis CI show green and the Travis CI test even installs everything with zef.

You've already fixed this in d80bd9e but the lastest released version 0.3.3, which gets downloaded by zef, is older than the fix. Please release a new version.
