[Boost-build] Problem with build-dir and foreign use-project

I'm developing a SDK system based on Boost Build v2.
I'm working with the Milestone 11 release candidate.
The following is a simple example of what I'm trying to achieve:

----------
* c:\build\Jamroot:

project build ;

use-project sdk : /c:/sdk ;

* c:\build\project\Jamfile:

exe project : /sdk//library ;

* c:\sdk\Jamfile:

project sdk ;

alias library : : : : <include>c:/ ;

----------

This setup works as expected.

But if I change the Jamroot file above to:

----------
* c:\build\Jamroot:

project build
    : build-dir bin
    ;

use-project sdk : /c:/sdk ;

----------

then bjam gives me the following error:

C:\build\project>bjam
c:/boost-build/util\path.jam:329: in path.relative from module path
error: /c:/sdk is not a subdir of /C:/build/project

c:\boost-build\kernel\bootstrap.jam:121: in boost-build from module
c:\boost-build\boost-build.jam:1: in module scope from module

I can't grok this error message.
What am I missing?
