benchmarking: cannot install pypy-devel

[dev2y]

Trying to install PyPy, using the following command.
PyPy: sudo dnf install pypy-devel

But I am getting the following error on CentOS9. Same error on Ubuntu. What I am missing?

dnf install pypy-devel
Last metadata expiration check: 1:09:41 ago on Fri 31 May 2024 10:51:30 AM PDT.
No match for argument: pypy-devel
Error: Unable to find a match: pypy-devel

I then installed it with apt install pypy3
Not sure, if this is the right way.

Later I tried to run the benchmark. pyperformance run -o py310.json

But it is failing with the following error. Proxy is set and no issues with installing any packages.
