Hi Phil,

thanks for rolling back the build. What are the desired target 
distributions for your wheels? That would determine the your build 
environment. There is e.g another issue related to OpenSSL. Ubuntu 22.04 
has switched to OpenSSL 3.x, which break TLS traffic with the Qt6 wheels 
provided via PyPI. That could be solved by installing an older OpenSSL 
1.x library from Ubuntu 21.10 (which is unfortunately gone by now). 
Fedora solved this differently by providing an OpenSSL 1.x compatibility 
package. In short, we should be prepared to see more of these issues in 
the future.
