Hi all,
I triggered a problem by writing a very simple python file, which only contains
one line :
--------
from sage.matrix.matrix_mod2_dense cimport Matrix_mod2_dense
--------
then, inside sage, running
sage: load "mini_problem.spyx"
raises an error :
sage: load "mini_problem.spyx"
Compiling ./mini_problem.spyx...
Error compiling cython file:

Is this a local problem ?
