Actually ... scraping the buildfarm to see what we're currently finding shows that the following machines are reporting that /usr/local/include/pythonN.N really is the include directory: conchuela curculio florican gombessa jabiru lapwing loach longfin marabou morepork peripatus plover Now, most of those are BSD machines --- but lapwing isn't. It says checking for python... (cached) /usr/bin/python configure: using python 3.6.9 (default, Jan 14 2022, 06:45:55) checking for Python distutils module... yes checking Python configuration directory... /usr/local/lib/python3.6/config-3.6m-i386-linux-gnu checking Python include directories... -I/usr/local/include/python3.6m checking how to link an embedded Python application... -L/usr/local/lib -lpython3.6m -lpthread -ldl -lutil -lrt -lm Not sure what to make of that --- maybe that's a handmade build? regards, tom lane
