I realize that, as it was discussed in the announcement thread:
but as I was able to get the tool chain to work and compile hundreds of modules (I’ve been using it exclusively for the past three months to keep my modules up to date) I figured it was actually supported-ish, although not officially.
But if you think that’s the issue, I’ll assume that it is! Strange that I didn’t have any issues on any of the other modules in my collection. Perhaps one of the modules in the Frozen Wasteland collection uses internationalization support in a way that none of the others do.
