I had the same issue, trying to compile latest svn trunk of boost.
When I bootstrap.sh-ed, it created project-config.jam which had my python
configuration in it (I provided --with-python-root=). Now, I also had
~/user-config.jam which had the exact same line ("using python : 2.6 :
/home/dan/stackless ;") and bjam wasn't sure which one of those to choose,
even though they were identical.
The solution for me was to remove the superfluous user-config.jam from my
home directory.
