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:

Looks like exactly the same problem as reported for the release candidate. Undoing those changes made it work again. Patch is attached for those who run into the same problem and want to build boost from trunk. I am not an expert for boost.build, but these changes seem to have broken the versioned layout.

[heller@faui32m trunk]$ ./b2 toolset=intel --layout=versioned -j2 variant=debug

It seems to work when using --layout=system

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