autoreconf: error: 'configure.ac' is required

The capital "N" in the worksrcdir looks suspicious to me, and I see that the port downloads Normaliz-3.10.0.tar.gz although the name of the download in the GitHub release is really normaliz-3.10.0.tar.gz. I guess GitHub's server allows case mismatches in names but we should not rely on that; most servers don't allow that. Probably the fix is to add distname ${name}-${version} to fix both the distname and the worksrcdir.
