Assistant: The error messages you're seeing indicate a failure in compiling the Mesa 3D Graphics Library (version 24.1.7) on your Gentoo system. Specifically, the Rust code in the `rusticl_opencl_bindings.rs` file attempts to perform operations that result in overflow errors, all related to attempts to compute `4_usize - 8_usize`.

Here's a breakdown of what's happening and some potential steps you can take to resolve the issues:

### Understanding the Issue

1. **Overflow Error**: The error messages like `attempt to compute 4_usize - 8_usize, which would overflow` indicate that there are attempts in the code to perform operations that result in negative values (unsafe in Rust, considering `usize` is an unsigned integer type).

2. **Rust Error E0080**: This specific error code stands for "evaluation of constant value failed". When constants are evaluated at compile time, certain errors can be caught early; arithmetic overflow is one of them.

### Possible Solutions

1. **Check for Updates**: Ensure your Rust toolchain is up to date, as newer versions might have fixes or improvements that could resolve these overflow issues.

2. **Patch the Code**: 
   - Modify the source code to prevent overflow. Instead of subtracting `8usize` directly, you could adjust the logic to ensure that the operation results in a non-negative number.
   - Alternatively, look for patches or bug reports in the Mesa project repository or Gentoo's bug tracker [aborted]
