Details:

nghttp2 uses the check:

AX_PYTHON_DEVEL([>= '3.8'])

But this fails because '3.10' < '3.8' in lexicographic order:

checking for a Python interpreter with version >= 3.8... python3
checking for python3... /usr/local/bin/python3
checking for python3 version... 3.10
checking for python3 prefix... /usr/local
checking for python3 exec_prefix... /usr/local
checking for python3 platform... linux
checking for python3 script directory...
${PYTHON_PREFIX}/lib/python3.10/site-packages
checking for python3 extension module directory...
${PYTHON_EXEC_PREFIX}/lib/python3.10/site-packages
checking for python3.10... (cached) /usr/local/bin/python3
checking for a version of Python >= '2.1.0'... yes
checking for a version of Python >= '3.8'... no
configure: error: this package requires Python >= '3.8'.
If you have it installed, but it isn't the default Python
interpreter in your system path, please pass the PYTHON_VERSION
variable to configure. See ``configure --help'' for reference.
