As you can see from the output above you are missing all of the Python
development libraries (eg. ‘python3-devel’ on Fedora).
On my machine with Python 3.6.2 and the correct development libraries
installed I see:
...
checking for python... /usr/bin/python3
checking Python version... 3.6
checking for PYTHON... yes
checking Python prefix... /usr
checking for Python site-packages path... /usr/lib64/python3.6/site-packages
checking for Python extension suffix (PEP-3149)...
.cpython-36m-x86_64-linux-gnu.so
checking for PyCapsule_New in -lc... yes
checking for PyString_AsString in -lc... no
