### Explanation of Changes

1. **Added Build Dependencies**:
   - `gcc`: Required for compiling C/C++ code.
   - `openssl-devel`: Provides headers and libraries for OpenSSL, which is used by the `ring` crate.
   - `pkg-config`: Helps locate libraries like OpenSSL during the build process.

2. **No Changes to Source Code**:
   - The issue lies in the build environment, not the source code itself. Adding the required dependencies ensures that the `ring` crate can compile successfully.

3. **Minimal Impact**:
   - Only the `BuildRequires` section of the `.spec` file was modified. No changes were made to the source code or other parts of the build process.

---

### Next Steps

1. Rebuild the package using the updated `.spec` file.
2. Verify that the `ring` crate compiles successfully.
3. If the issue persists, further debugging may be required to identify missing configurations or environment-specific issues.
