That shouldn't be necessary.

First run:

* Run the compiler once with the -deps flag to collect the dependencies
* Run the compiler again to compile everything
* Cache dependencies

Later runs:

* Run the compiler once with the -deps flag and compile everything
* If the dependencies have change run the compiler again
* Re-cache the dependencies if necessary
