rpds in Python-bundle-PyPI-2024.06-GCCcore-13.3.0 fails install on missing maturin

[mmterpstra]

Hi easybuilders,

I donk know the exact origin of the problem but on my hpc infra the build of Python-bundle-PyPI fails in rpds extension installation due to undetected maturin. I'm leaving this here because it might help the community.

Relevant easybuild:

easybuild-easyconfigs/easybuild/easyconfigs/p/Python-bundle-PyPI/Python-bundle-PyPI-2024.06-GCCcore-13.3.0.eb

Line 524 in ce73734

('rpds-py', '0.18.1', {

Quick fix for me:
Moving maturin from builddependencies to regular dependencies.

Error:
