As per:
linuxcnc.org/docs/html/drivers/hal_pi_gpio.html
7. Known Bugs
At the moment (2023-07-16) this driver only seems to work on Raspbian as the generic Debian image does not set up the correct interfaces in /dev/gpiomem and restricts access to the /sys/mem interface.

HAL_PI_GPIO: can't open /dev/gpiomem: 2 - No such file or directory
If the error is 'permission denied' then try adding the user who runs
LinuxCNC to the gpio group: sudo gpasswd -a username gpio
HAL_PI_GPIO: can't open /dev/mem: 13 - Permission denied
hal_pi_gpio: rtapi_app_main: Operation not permitted (-1)sudo gpasswd -a username gpioPlease Log in or Create an account to join the conversation.

The error is
HAL_PI_GPIO: can't open /dev/gpiomem: 2 - No such file or directory
/dev/gpiomem doesn't exist
A replied previously
At the moment (2023-07-16) this driver only seems to work on Raspbian as the generic Debian image does not set up the correct interfaces in /dev/gpiomem and restricts access to the /sys/mem interface.
So have will have to start with a Raspbian image, build & install a rt kernel and then build & install linuxcnc.
But just for completeness can you run
and report the result

This problem was already known:
forum.linuxcnc.org/9-installing-linuxcnc...-pi-5?start=0#285243
My advice is to use this new module (hal_gpio) which, in addition to working on Pi 5, in my opinion is more versatile and easier to configure
For changes to be made to .hal files it may be useful to refer to this video
