Thanks for the report. Ideally this is something you'd take up with [tweedledum](https://github.com/boschmitt/tweedledum) rather than us, but as far as I know, Bruno (the maintainer) has been rather busy recently,...

It's quite possible that the build requires having specific C compiler tooling and potentially various header files of C/Fortran libraries available on your system, which may be why you're struggling...
