Yeah it’s known limitation of rust on musl, you have to add custom rustflags, check rust’s postinst message. I’ll reach out on IRC to guide you how to do that, otherwise tou gonna file a lot more similar bugs :-)
closing, please add RUSTFLAGS="-C target-feature=-crt-static" to make.conf on musl, like discussed on IRC. rust on musl compiles static binaries by default and above setting changes it to dynamic, as some crates can't be compiled as static and everything that depends on those crates will fail like that, that's known limitation and musl users know it (unless they use smaeul's fork with already does this internally by default)
