What's your emerge -pv virtual/rust output, and for your Rust package of choice? The profiler USE flag should be enforced for Rust, so the problem should not exist to begin with.

dev-lang/rust-bin包似乎缺失libprofiler相关文件.
同时发现rust-lang.org提供的包,stable(1.79.0),beta也缺失.
只有nightly包提供了libprofiler(chromium在尝试构建中)
缺失的原因未知

dev-lang/rust-bin doesn't contain profiler bits for loong until 1.81.0: my fix PR

until then (2024-09-05 UTC), use dev-lang/rust
