Well, on Windows, DLL is a pair of targets -- DLL and import lib. On Linux, 
with current CVS, you'd get a different error:

   In 'install': <name> property specified with target that requires relinking

Generally speaking, on Linux, if you change a name of a shared library, you 
need to relink all other libraries and executable files that refer to it.

Of course, this is not needed for plugins, but Boost.Build does not know if 
this is plugin, or not, and I don't know an easy way to detect if there are 
other libraries linking to this one. And this restriction probably does not 
makes sense for Windows, but we don't distinguish this case yet.

Am I right that this is plugin for a specific tool, and the extension should 
always be ".mll". Then you can just do this:

  import type ;
  type.register MLL : mll : SHARED_LIB ;

you can put this code in Jamroot, and then use this:

  mll MY_Blend
    # sources
    : [ glob ./src/*.cpp ]
      Foundation OpenMaya OpenMayaAnim 
    :
      <include>./src
      <link>shared
    ;

That's from memory, but should work, and won't require renaming library on 
install time.
