   Does something like the following do what you want:

   install my-dist
     :
         ...my-targets-to-install...
     :
         <variant>debug:location>debug-location
         <variant>profile:<location>profile-location
         <variant>release:<location>release-location ;

   Alternatively, if you need a more complex condition you can look into 
using functional properties like <location>@my-location-rule. I might 
have gotten the syntax wrong here but it should be easy to find in the docs.

   You can condition your location on multiple properties ofcourse like in:

   <variant>debug/<os>AIX:<location>somethere-over-the-rainbow

   Again... writing this from memory so it might be wrong (e.g. might be 
, instead of /)... but it should not be hard to test and/or find in the 
documentation.

   Hope this helps.
