So I am trying to compile python 3.7.3 on debian 9.9, got all the libraries installed and previously I was getting an uuid module error which was then fixed by finding this 'tweak':

--- Modules/_uuidmodule.c.orig
+++ Modules/_uuidmodule.c
@@ -3,8 +3,7 @@
 #include "Python.h"
 #ifdef HAVE_UUID_UUID_H
 #include <uuid/uuid.h>
-#endif
-#ifdef HAVE_UUID_H
+#elif defined(HAVE_UUID_H)
 #include <uuid.h>
 #endif

however now I am puzzled as I am getting a different error and have no idea how to go about it:

Any help would be greatly appreciated as I am keen to start learning and never thought getting the newest version could be so complicated
