          =============================DEBUG ASSISTANCE=============================
          If you are seeing a compilation error please try the following steps to
          successfully install bcrypt:
          1) Upgrade to the latest pip and try again. This will fix errors for most
             users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
          2) Ensure you have a recent Rust toolchain installed. bcrypt requires
             rustc >= 1.56.0.
      
          Python: 3.9.2
          platform: Linux-5.15.76-v8+-aarch64-with-glibc2.31
          pip: n/a
          setuptools: 66.1.1
          setuptools_rust: 1.5.2
          rustc: 1.48.0 (471d696c7 2020-12-10)

      error: Rust 1.48.0 does not match extension requirement >=1.56.0

  note: This error originates from a subprocess, and is likely not a problem with pip.

[webattitude]

Ok hi
I guess it's because bcrypt is now in Rust, and minimum version required is not available in bullseye...

[guysoft]

Indeed, and the rust shipped in debian bullseye is too old. so for now Fixed with this commit:
guysoft/CustomPiOS@d8c6380

If you have any better idea would love to hear
