I’ve observed on my M1 box that stack-based ports no longer build because of compiler issues with mixed architecture libraries, as more ports become native ARM. I’ve done enough troubleshooting (reinstalling CLT, Xcode, use_code=yes and so forth) to believe that this is a general problem—error messages are below.
Regarding the libunwind error you're seeing, this is because stack/alex is linking with the libunwind in /opt/local/lib but doesn't declare a dependency on the libunwind port. If a dependency were declared, the port would be installed +universal when needed.
But I think a dependency is not appropriate because the system libunwind is probably fine, as it is for most ports. The libunwind port installs an older version which I think is intended to be used on systems that are even older. I'm not sure if all the ports that do declare deps on libunwind really need it, but I think it might be best to install libunwind somewhere other than /opt/local/lib so that innocent bystanders don't accidentally link with it.
