Thanks @jamespdo I'll need to figure out the build issue first then I can merge. Cheers for this. :) cc: @irobayna.

@murakamit I'm not sure what you are saying here. Indeed this pull request solves a problem. If you do not apply it, if the fix is not applied it is expected you will still have the issue. I might be misunderstanding you.

This is still in place in the currently published gem (1.7.0) is there going to be a new release or should we be pointing to master when installing this gem?

[jamespdo]

@gerrywastaken can you release new version which include this merge? or release 1.7.1 to patch if its not ready?
