+	# a failure at make install on a python-free system. Since none of

+	# solution. The failing lib is install later in the process, so
+	# even if the compilation is failing without the patch, with it, the
+	# target python is fully functionnal.
+	# The "-i" will have to be removed when the bug will be solved.
