Unfortunately, it seems that, different from all other build systems I'm aware of, bjam doesn't print out a summary of what it will be doing. I tried many variations of syntax, but apparently it never worked out.
No build system I know produces summary of that it *will* be doing. Some build systems echo the commands before executing them, but definitely not all -- for example, CMake does not print complete commands either. You can make Boost.Build to print commands using -d2 option.
I didn't mean the build-system as such, but the concrete instance: For example building CLisp I get a summary: Here are all the instructions you gave as (and as we understand them!), here are our findings about your system, and here is what we are going to do.

Thanks for this information! This page is valuable. Now I activated more informative output via -d+2 --debug-configuration --debug-building (not clear what I really need), and I see notice: [cmdline-cfg] Detected command-line request for gcc-4.1.2: toolset= gcc version= 4.1.2 notice: [cmdline-cfg] toolset gcc-4.1.2 not previously configured; attempting to auto-configure now notice: will use 'g++' for gcc, condition <toolset>gcc-4.1.2 notice: using gcc libraries :: <toolset>gcc-4.1.2 :: /usr/local/bin /usr/local/lib /usr/local/lib32 /usr/local/lib64 This is definitely not what I want: So the remaining open problems is how to get my *local* gcc working? Apparently --toolset=gcc-4.1.2 --toolset-root=PATH-TO-LOCAL-INSTALLATION --"-sGCC_ROOT_DIRECTORY=PATH-TO-LOCAL-INSTALLATION" which used to work for boost 1_34_1, is no longer working. According to http://www.boost.org/boost-build2/doc/html/bbv2/advanced/configuration.html all what I need to do instead seems to tell bjam the full path to my g++ (and then apparently it figures out the rest): Can this information be passed as a parameter, or is such a .jam-file needed?
3) No python; this seems also unproblematic (but apparently it vanished from the documentation?)
--without-python
It is present in "--help" output.
But it "python" a library? Thanks! Oliver
