Thanks for the pointer, that helps. A few items of note and further
(1) On Windows (with MSVC 7.1, 8, and 9), a nearly identical build
command, without the layout option, works just fine.
(2) According to bjam --help (run from the Boost directory),
"versioned" is the default layout. Apparently this is just a
documentation error, though, because when I specified "versioned"
explicitly, the error I had went away on both Linux and Macintosh.
(3) On Linux, all is now well.
(4) On Macintosh, your suggestion solves my original error, but gives
me new trouble because I'm trying to create universal binaries under
Snow Leopard. But since I see another thread that covers that issue,
there is no need to rehash it here.
So, bottom line: There is a minor documentation bug in the text
emitted by "bjam --help" regarding the default for the --layout option.
