Hey Mark, I wasn't doing a cross-build, but rather a native build for amd64. I'm getting errors again. In fact, I'm getting the same error you just posted above. I have no clue why the error's happening. That you're also getting the error shows that the issue isn't specific to HardenedBSD at the very least.
