Strange error building on Rawhide

Hey all-

I’m trying to build Swift 6 on Rawhide and it looks like it gets to the very end, to the %install section, then errors out with:

``` + /usr/bin/add-determinism --brp -j4 /home/rolson/rpmbuild/BUILD/swift-lang-6.0-build/BUILDROOT Error: Path "/home/rolson/rpmbuild/BUILD/swift-lang-6.0-build/BUILDROOT" is outside of $RPM_BUILD_ROOT error: Bad exit status from /var/tmp/rpm-tmp.EbjPHr (%install) ```

Never, ever seen that particular message. I’m assuming the RPM build tools on Rawhide are newer and perhaps there’s something I should be adding to my spec file that I’m not aware of, as often is the case. :\

Thanks for any help,

Ron
