Hi! In discussion with Christian Stump and Nicolas Thiery, I learned that the way to fix a problem when sage remembers a wrong link (for example, in Tom's case with affine permutations, he previously had the file in a directory /combinat/affine_permutations/affine_permutations.py and changed it to a file in /combinat/affine_permutations.py), you need to remove the old links by hand.
Make a small change somewhere, run sage -br Then sage tells you where it puts the files. For me: ... copying build/lib.macosx-10.6-x86_64-2.7/sage/combinat/affine_permutations/affine_permutations.py -> /Applications/sage-5.5/local/lib/python2.7/site-packages/sage/combinat/affine_permutations copying build/lib.macosx-10.6-x86_64-2.7/sage/combinat/affine_permutations/all.py -> /Applications/sage-5.5/local/lib/python2.7/site-packages/sage/combinat/affine_permutations I had to remove the directory affine_permutations in these directories by hand. Then it works.
