Hi,

I am trying to build current trunk with layout versioned. Boost build is 
currently failing. This looks similar to the problem reported with the 
1.50 RC.
Here is the error:
[heller_at_faui32m trunk]$ ./b2 toolset=intel --layout=versioned -j2 
variant=debug

Building the Boost C++ Libraries.

It seems to work when using --layout=system

Anyone knows a fix to this? FWIW, toolset=gcc has the same problem

Thanks,
