[boost] [build] referring to a tool from an external project

Subject: [boost] [build] referring to a tool from an external project

I'm trying to write a jamfile in an external project that uses boost.
The jamfile should invoke the wave tool to preprocess some code as a
build action. I have this:

actions do_wave
{
  $(>[2]) -o- --config-file wave.cfg $(>[1])
}

W = /boost/libs/wave/tool/build//wave ;

make preprocess
  : preprocess.cpp $(W) : do_wave
  ;

I get:

> error: Unable to find file or target named
> error:     '/boost/libs/wave/tool/build//wave'
> error: referred to from project at
> error:     '.'
> error: could not resolve project reference '/boost/libs/wave/tool/build'

If I use this instead:

W = /boost//wave

...it builds the wave dlls, not the command-line tool. So how do I tell
it to build the tool?
