I've attached a test case that demonstrates the problem.  The test case 
now includes a patch to package.jam as well, which I forgot I had to fix.

Follow these steps:

1.  Untar boost-install-test-case.tar into a fresh boost-1.35 directory.

2.  cd to $(BOOST_ROOT)/libs/install-test-case/build and run:

        bjam --v2 install

     Watch bjam complain.

3.  Apply patch Jamroot.diff to $(BOOST_ROOT)/Jamroot and 
package.jam.diff to $(BOOST_ROOT)/tools/build/v2/tools/package.jam

4.  Run bjam again and see that it works this time.
