I'm trying to make some documentation for a project that uses boost.build v2.  I'm getting the error:

I have:
docs/Jamfile
using xsltproc ; 
using boostbook ;
using fop : /usr/bin/fop : : /usr/bin/java  ; 
using quickbook : /home/build/boost_1_39_0/dist/bin/quickbook ;                                                 
xml my_doc : my_doc.qbk ;                                                                  
boostbook standalone : my_doc :

I narrowed the problem down to having a ../project-config.jam.  This is being detected as the root-project in rule xml-catalog ( ) in tools/boostbook.jam.  If I remove the project-config.jam, it correctly detects the build path and goes correctly.  Is my use wrong or is there something else I can do to work around this?  I tried adding a project in the docs jamfile, but it did not seem to help.
