OpenSUSE is not a targeted OS, so not something we would worry about.

But, the issue you are running into is building python dependencies from source and you would have to provide their dependencies to build, which can be unique for every dependency.

[fwag]

I'm aware of it but I wanted to create an RPM for OpenSUSE too as I love this tool.
I don't get why it expects proj to be present while installing it
proj executable not found. Please set the PROJ_DIR variable. For more information see: https://pyproj4.github.io/pyproj/stable/installation.html

[bharnden]

I noted above as to why, the dependency is being built from source, so that question would be to them on why they need that to build.
