Okay, so the rpm has it's usual provides and requires, in this case a requirement for python38. Still, I don't really understand how it can work for a simple example I have in mind. Let's say there is this new, shiny Apache httpd version 3.0.0 which requires this new and incompatible zlib version 2.0.0. How can this be built with modules? Dozen of RPMs depend on zlib version 1.x.x, how is this situation handled with modules. Sorry, I just don't really understand. Thanks, Simon
