After doing a little more searching in the issues here I can verify this workaround at least lets me build: #41

Would be nice if the documentation called out some troubleshooting tips.

Hi @tbeech , sorry for the delay replying. Indeed we still need to have a proper troubleshooting documentation. This is something we'll trying to fix in the short term future. Let us know if you have any other issue with this library.
