Thank you for contributing to this driver. However, before opening pull requests to fix compilation errors, please have a look at the continuous integration builds. As you can see there, the testing and semi-binary builds are succeeding, which indicates, that no code changes are necessary in order to successfully build the package.

As our installation documentation states, building head from source might require building direct dependencies from source, as well. In this case, we've recently added MODE_TORQUE to the client library, which is not synchronized to the main repo, yet.

I'll close this PR, as there is no change necessary.
