Can you open Jamroot and see how many lines of the form:

        class top-level-target : alias-target-class

you have? If more than one, your Jamroot is busted. Do you have,
in root source dir, files named [Jj]jamroot.jam, or project-root.jam?

If nothing works, add --debug-loading to bjam command line and
post the output.
