Circular Dependency Definition Woes

I have a list of ml files, and some interfaces in mli; I'm compiling a cma and cmxa successfully, but there's a target that consumes the library that keeps complaining:
No implementations provided for the following modules:module, module module...
But there are implementations provided for every single one of those modules. There are circular dependencies between them, hence the mli files, but I don't know how to get the compiler to accept that there are definitions. So the library compiles fine, but the actual target does not.
I am, however, seeing this:make[2]: Circular source1.cmx <- source2.cmx dependency dropped.
a lot. And it's clear that looking at the error output that for every one of those lines I see, that there will be a corresponding complaint.
Is there any way to get past those circular dependencies?
