checking XCBPROTO_XCBPYTHONDIR... /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

XCBPROTO_XCBPYTHONDIR is determined by the Python version used to build xorg-xcb-proto. If you build/activate xorg-xcb-proto +python37 beforehand, XCBPROTO_XCBPYTHONDIR will be /opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages.

xorg-xcb-proto: update python dependencies

• Make python37 variant the default
• Make python depends_build only. Python is not necessary to use ports

depending on XCB. Instead, python is used to build xorg-libxcb only.

• Remove python34. Python 3.4 has reached EOL on March 18, 2019.
