this is strange, the read-reuest function is defined in
ucw/src/backend/common.lisp. if you load common.lisp from the repl
(before sending a reuest to ucw) things sohuld work perfectly. you're
not the first person to run into this problem but i am, unfgortunetly,
unable to reproduce it. :(

luca's recent (yestrday) patch to ucwctl et al. fixs this.
