If you installed python via your package manager then perhaps you are
simply missing the python-devel package, exact name will depend on your

This is the path to the python-config script that will say how to build
against the python libraries. E.g

$ which python-config 

[ side note
It outputs something like...

$ python-config --cflags --libs
-I/usr/include/python3.10 -I/usr/include/python3.10  -Wno-unused-result
-Wsign-compare  -O2  -fexceptions -g -grecord-gcc-switches -pipe -Wall
-Werror=format-security -Wp,-D_FORTIFY_SOURCE=2
-Wp,-D_GLIBCXX_ASSERTIONS  -fstack-protector-strong   -m64
-mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection
-fcf-protection -D_GNU_SOURCE -fPIC -fwrapv
-grecord-gcc-switches -pipe -Wall -Werror=format-security
-fstack-protector-strong   -m64  -mtune=generic
-fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection
-D_GNU_SOURCE -fPIC -fwrapv -lcrypt -ldl  -lm -lm

all that gets passed to the compiler command.

You may need this depending on how you installed python.

I assume you can use this to say where unit can find the python DSO, e.g

$ locate

That's from the Python3 package installed on Fedora.

Again, if you've installed python in a non-standard location you may
need to specify this.
