Is the problem that an example does not compile? If so, please report that via http://svn.boost.org -- however, unless you specifically need that example it does not seem to be showstopper.
Unrelated to that, you don't seem to be using the official build procedure documented at:
http://boost.org/more/getting_started.html
That procedure does not builds examples for every library by default.

Volodya, I saw that you are supposed to use the bootstrap script, but it seemed reasonable to make a bin directory, and from there run ccmake on the boost-trunk directory. There was no option in the cmake configuration to not build examples. Maybe this can be added for users who wish to use this procedure. I got around it by just using 'make -k'. I also reported the accumulator example bug on the bug tracker. Thanks for the quick reply, David
