Here is the solution: Create an empty file __init__.py in .../sage/algebras/letterplace/, for examply with touch sage/algebras/letterplace/__init__.py (when you are in SAGE_ROOT/devel/sage/)
Then, sage -br should do the trick. Once again, I forgot to include __init__.py in a patch. I will update it on trac tomorrow.
