Hi Phil.

I presume you're on Linux, which distribution?

I just tried it here on Debian 12 and everything works as expected.  I
have the 'python3-dev' package installed which *should* pull in
everything else (header files, etc.).  Here is my 'configure' excerpt:

../hamlib/configure --prefix=$HOME/local --with-python-binding

...

checking whether to build python binding... yes
checking for python... /usr/bin/python
checking for a version of Python >= '2.1.0'... yes
checking for a version of Python >='2.1'... yes
checking for the sysconfig Python package... yes
checking for Python include path... -I/usr/include/python3.11
checking for Python library path... -L/usr/lib/x86_64-linux-gnu -lpython3.11
checking for Python site-packages path... /home/nate/local/lib/python3.11/site-packages
checking for Python platform specific site-packages path... /home/nate/local/lib/python3.11/site-packages
checking python extra libraries... -ldl -lm
checking python extra linking flags... -Xlinker -export-dynamic -Wl,-O1 -Wl,-Bsymbolic-functions
checking consistency of all components of python development environment... yes
checking whether /usr/bin/python version is >= 2.1... yes
checking for /usr/bin/python version... 3.11
checking for /usr/bin/python platform... linux
checking for GNU default /usr/bin/python prefix... ${prefix}
checking for GNU default /usr/bin/python exec_prefix... ${exec_prefix}
checking for /usr/bin/python script directory (pythondir)... ${PYTHON_PREFIX}/lib/python3.11/site-packages
checking for /usr/bin/python extension module directory (pyexecdir)... ${PYTHON_EXEC_PREFIX}/lib/python3.11/site-packages

...

 Package features:
    With C++ binding		    yes
    With Perl binding		    no
    With Python binding 	    yes
    With TCL binding		    no
    With Lua binding		    no
    With rigmem XML support	    no
    With Readline support	    yes
    With INDI support		    no

...

Then 'make' and 'make install'.

And since I am installing into my home directory I have the following
file:

$HOME/.local/lib/python3.11/site-packages/home_local.pth

which contains:

/home/nate/local/lib/python3.11/site-packages

I successfully ran 'py3test.py' from the bindings directory.
