Version 3.1 of mod_wsgi can be obtained from:
http://modwsgi.googlecode.com/files/mod_wsgi-3.1.tar.gz
As this version follows on quickly from mod_wsgi 3.0, ensure you read:
1. Ensure that any compiler flags supplied via the CFLAGS environment variable when running 'configure' script are prefixed by '-Wc,' before being passed to 'apxs' to build module. Without this 'apxs' will incorrectly interpret the compiler options. For more details see:
https://code.google.com/archive/p/modwsgi/issues/166
1. Now give more explicit error message when compilation fails due to the Apache or Python developer header files not being installed. See:
https://code.google.com/archive/p/modwsgi/issues/169
