Integrating Boost with STLPort

I'm a little confused with the documentation (or lack thereof). Just need one clarification.

Seems to be a no brainer that I need to use the gcc-stlport toolset to build boost for the GCC with the stlport. But then I'm confronted with the fact it is possible to build the STLPort with boost support by defining STLP_BUILD_BOOST_PATH.

I have both boost and the stlport port for a while, but they weren't build for support of each other. I want to change that, for both.

Is it irrelevant which I build first? Boost with STLPort support, or STLPort with boost support?

Nevermind. Found the answer in user_config.h.
