That's not going to work. The *PACKAGE* variable is rebound by LOAD and
COMPILE-FILE, and the IN-PACKAGE form in your package.lisp won't affect
further loading/compiling.

You have to (fsvo "have to", at least) put the appropriate IN-PACKAGE
form to the beginning of each file. That will also cope much better with
your development environment.
