checking for PYGOBJECT... configure: error: Package requirements (pygobject-2.0 >= 2.11.1) were not met:

Requested 'pygobject-2.0 >= 2.11.1' but version of PyGObject is 2.8.6

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables PYGOBJECT_CFLAGS
and PYGOBJECT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
