[Boost-users] documentation build problem

I get the following error when I try to build any documentation with boost 1.41: cat "/tmp/jam112c3106.000" > "/bin/boostbook_catalog.xml" obviously it can't copy to /bin/, but BOOST_ROOT is set. not only is the root missing from the directory, but the bin directory is called "bin.v2", not "bin". I can't figure out where this "cat" is coming from or how to set the path correctly. can anyone help me with this?
