I think I know why it worked before. Before the change the boost/mpl directory
was a link to libs/mpl/include/boost/mpl. The link was created due to a
dependency on some public MPL header, but it 'installed' all MPL headers,
including those that were not discovered by Boost.Build due to preprocessor
tricks. Now every file in boost/mpl is a link, and the problem appears on the
