I think that many of the import statements in free_module.py should be inside the methods that use them, rather than at the top level. Here's a patch which moves some of them: <http://sage.math.washington.edu/home/palmieri/misc/cfm.patch> I think this should make it work. I tested this by adding a line from sage.categories.examples.algebras_with_basis import Example to sage.rings.all, and Sage started without problems. (I may also have had to fix some imports in examples/algebras_with_basis.py.) -- John -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
