'pip install numpy' creates directories with wrong permissions

The command 'sudo pip install numpy' creates directories numpy, numpy-1.24.3.dist-info and numpy.libs under /usr/local/lib/python3.8/dist-packages/
All these directories and files therein are read-protected for regular users, so those users cannot use numpy.
Previous (older) installations of other python packages did not have this problem.
On another computer with ubuntu 22.04, pip creates files and directories with read permission for everybody and numpy works OK.

Should I report this as a bug ?
