I have tried setting permissions for /home/sherman/modules/Sudoku/ExistingNumbers.pm to 775 and 777 but nothing seems to work.

Check also that you can execute (see chmod a+x) all the parent directories. It is a common mistake.

chown sherman:sherman ~/modules/
chown sherman:sherman ~/modules/Sudoku/
