One guess is that during doctesting from doctesting another version of Sage, the file "multiprocessing.py" got copied to /home/jec/.sage/tmp/ multiprocessing.py, and this is confusing Python: it should try importing from the standard Python module "multiprocessing", but instead it looks in this file. So I think you should delete it. (The Sage library file multiprocessing.py has since been renamed to "multiprocessing_sage.py", basically for this reason.) -- John -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
