Hi again, what I just did was:
Remove the build directories for letterplace: $ rm -r build/temp.linux-x86_64-2.6/sage/algebras/letterplace/ $ rm -r build/sage/algebras/letterplace/ $ rm -r build/lib.linux-x86_64-2.6/sage/algebras/letterplace/ $ rm -r sage/algebras/letterplace/ Apply the patch: $ hg qpush Wende trac7797-full_letterplace_wrapper.patch an jetzt bei: trac7797-full_letterplace_wrapper.patch $ ls sage/algebras/letterplace/ free_algebra_element_letterplace.pxd free_algebra_letterplace.pyx free_algebra_element_letterplace.pyx letterplace_ideal.pyx free_algebra_letterplace.pxd So, everything is put in place by the patch (in particular, the pxd- files are!). But then, I get the same error as you when I do "sage -b". Strange. Do other people have an idea what happened?
