I am going with the guess  that your CFFI install is still not straight. The
string "to-c-dynamic-expander" does not appear in my CFFI source tree, but
it does appear in an old directory helpfully named cffi-pre-2006-04. This
would be consistent with you having a mix of code now, in which some of it
is old and still looking for that slot, while some of it is new and no
longer has that slot. Of course I do see "to-c" stuff in the new tree
because CFFI has a lot of built-in abilities that way, but I have to think
they refactored recently.
