ASDF: constants

How should I deal with constants when using ASDF?

My problem:

 a.lisp <-- defines a structure and some constant structures
 b.lisp <-- need the constants

However, when it try to load the system, it seems that the constructor is
not defined by the time the system tries to initialize the constant.

I have currently solved this by putting the constants into a separate file
that depends on a.lisp, but is this the "correct" solution?

Cheers,
