No such luck. After reinstalling libffi-dev:

   - ECL_CONFIGURE="--with-libffi-prefix=`pwd`/local"  ./sage -i ecl  does 
   nothing (cyles through the configuration twice)
   - ECL_CONFIGURE="--with-libffi-prefix=`pwd`/local"  ./sage -f ecl 
   *FAILS,* with an error similar to previous attempts:

I'm leaving this for tonight (re-switching to my many-times upgraded tree). 
Let me know if you need further tests.
