   I'll pin `pyproject-metadata==0.8.1`.
   
   > Could you show some evidence to support your fix? Like why the specific 
version 0.4.1 and 0.9.0? What is the dependency chain? What did not work when 
we didn't pin the version?
   
   ### Regarding beniget
   
   scipy uses pythran (`>=0.12.0,<0.13.0`) during its build process. pythran 
0.12.x requires `gast<=0.5.3` and `beniget~=0.4.0` as dependencies.
   
   - pythran 0.12.2 requirements.txt: 
https://github.com/serge-sans-paille/pythran/blob/0.12.2/requirements.txt
   
   beniget 0.4.2 and later added code to handle Python 3.10 match statement AST 
nodes (`MatchStar`, `MatchAs`), but these nodes were only implemented in `gast 
0.5.4`. Since pythran constrains gast to `<=0.5.3`, the combination of beniget 
0.4.2 + gast 0.5.3 results in the following error:
   
   ```
   AttributeError: module 'gast' has no attribute 'MatchStar'
   ```
   
   - beniget issue (bug report): 
https://github.com/serge-sans-paille/beniget/issues/108
   - gast 0.5.4 diff where MatchStar was added: 
https://github.com/serge-sans-paille/gast/compare/0.5.3...0.5.4#diff-44b67094998a7df1e5ce843b5a2faa44950f5896ac9e07ab99d09e2b24c90143R328
   
   Upgrading gast to 0.5.4 or later is not possible because it violates 
pythran's constraint. Pinning beniget==0.4.1 is the only solution.
   
   
   ### Regarding pyproject-metadata
   
   scipy's build system, meson-python, uses pyproject-metadata for metadata 
processing. pyproject-metadata 0.9.0 introduced breaking changes for PEP 639 
support and implicitly requires `packaging>=23.2` (this requirement is not 
correctly recorded in the package metadata due to a bug).
   
   The older version of meson-python used in the Dockerfile environment is not 
compatible with the API changes in pyproject-metadata 0.9.0, causing the build 
to fail at the metadata generation stage. Pinning pyproject-metadata==0.8.1 
maintains compatibility with the existing meson-python version.
   
   - meson-python changelog (notes that 0.18.0 bumped the minimum 
pyproject-metadata requirement to 0.9.0, and mentions the packaging version 
requirement bug in 0.9.1): https://mesonbuild.com/meson-python/changelog.html
