[Boost-build] Run target dependency on exe without getting transitive usage requirements

Subject: [Boost-build] Run target dependency on exe without getting transitive usage requirements

I have a run target that needs to wait until an exe is built before it runs. When I pass it as <dependency> it adds all the exe's usage 
requirements (almost all of which are propagated from the exe's own lib dependencies) to the run target. How do I avoid that? Is this by 
design? Shouldn't depending on an exe only propagate the exe's own usage-requirements, not any transitive usage-requirements?

Thanks,
