Error with `list_clone.c`

edit

When I run sage in my laptop I get this error messages:

patching /home/koutsis/SageMath/src/build/cythonized/sage/structure/list_clone.c

Traceback (most recent call last):

File "/home/koutsis/SageMath/relocate-once.py", line 85, in <module> p('src/build/cythonized/sage/structure/list_clone.c').substitute().save()

File "/home/koutsis/SageMath/relocate-once.py", line 51, in save with open(self.filename, 'wb') as f:

IOError: [Errno 13] Permission denied: '/home/koutsis/SageMath/src/build/cythonized/sage/structure/list_clone.c'

That may not allow me to use git in my sage file!
