Actually, "use-project" takes an id and directory, so "./$(d)" would use
"./a" as the project id of the sub-directory "a". I always have to look
up the order. :-)

Anyway, it turns out that the problem may be with the "[ path.glob * :
Jamfile ]" part. When I run bjam in the same directory as the Jamfile
containing that code, it finds the sub-directories with Jamfile's in
them. If I run it in one of the child directories, path.glob returns
nothing. Is something broken in "path.glob"? It looks to me like it's
using the current directory instead of the directory the Jamfile is in.
