If you're really brave, you can take the attached patch, apply it to your 
Boost.Build, and then use something like:

  exe a : a.cpp ;

  install dist : a : <indirect-conditional>$(__name__).mess-with-properties ;

  rule mess-with-properties ( properties * )
  {
      if <variant>debug in $(properties)
       {
           return <location>MYDEBUG ;
       }
  }

The patch is work-in-progress on http://zigzag.cs.msu.su/boost.build/ticket/23 
and will be done in a couple of days, so you might just wait a bit until the 
interface and semantics is finalized.
