[boost] [build] error: No best alternative for ./install

Hi, I am trying to test trunk against external projects using boost. But "bjam install" has stopped working recently on my Linux box. $ sudo ./bjam install error: No best alternative for ./install next alternative: required properties: (empty) matched next alternative: required properties: (empty) matched ...found 1 target... I have no idea what this means and is basically stuck. Any help? -- Bjørn
