Yes Dave, that's correct.

Although you could hard code it to python3.7m, I"d suggest a
version-independent mechanism like changing the existing line:
    -e "/usr/include/python$PYTHONVER" \
to:
    -e $(pkg-config --cflags-only-I python3 | sed -e 's/^-I//' ) \

This uses pkg-config to find the "official" include path and strips the
leading '-I'. Then sip.h would be installed in the correct location
regardless of the python version.
