Reminder: I don't have 'python3 gi'

Python 3 gi is already the latest version (3.30.4-1).
I don't know where the problem is.

you can run
dpkg-checkbuilddeps
to see what is missing.

Here is a video I did of the build process which may help. It shows how to use dpkg-checkbuilddeps

I have run 'dpkg-checkbuilddeps' 
 
This shows that the dependency should have been installed

hmmm that was interesting.

I have python3 installed, this is the line that runs the check where you are failing, I added the python3 bit, the original line is
if $PYTHON -c "import gi;gi.require_version('Pango', '1.0');from gi.repository import Pango"; then
.
python3 -c "import gi;gi.require_version('Pango', '1.0');from gi.repository import Pango"
was ok
[code]python -c "import gi;gi.require_version('Pango', '1.0');from gi.repository import Pango"
failed

After linking /usr/bin/ptyhon3 to /usr/bin/python
[code]python -c "import gi;gi.require_version('Pango', '1.0');from gi.repository import Pango"
was ok
 What does [code]python --version[/return] ?

Does Buster have both python3 & python2.x installed ?

I followed the video to operate. When I execute 'sudo./configure -- with real-time=uspace'

When, the system will prompt me to install 'Python 3 gi', but I have this module in my system, so I don't know how to solve this problem.
 
When I execute 'sudo./configure -- with real-time=uspace' again
 
Remind me again that I need to install 'python3 gi'

I would recommend you build linuxcnc on a Bookworm installation. 
I built an installer which do it all for you.
This will include linuxcnc 2.9 installed as a deb but that is the whole point of the rip-environment command. It will override the 2.9 settings while that window is opened.

If you do build 2.9 debs, I always first uninstall what is there 
sudo apt remove linuxcnc-uspace linuxcnc-uspace-dev
Then reinstall the new ones you built (replace the x's with the full deb name with cut and paste)
sudo dpkg -i linuxcnc-uspacexxxxxx
sudo dpkg -i linuxcnc-uspace-devxxxxxx
