Getting issue while building custom python package 23.05

I have recently upgraded from openwrt21.02 to openwrt23.05 (upgrade planned to 24.x)
I have a custom git rep python package which has setup.py and set of files which needs to be installed. they are present in feeds package which installs git repo and set of python files

Following was working with 3.9 however with openwrt 23.05, 3.11 python this complains about .whl unable to find it.
I know that with 3.11 stricter pep enforcements have been enforced. How can this be solved?

Start with feeds/mfw/runtests/Makefile at the failing line 47 and compare its wheel path with the wheel filename produced by setup.py. Run the runtests package build on OpenWrt 23.05 and inspect the generated wheel and installer command. Done means the package build locates the generated wheel and completes installation.
