>Description:
   The generated user-conf.jam is not found by bjam, resulting in:
        ===> Building for boost-python-1.34.1
        python: not found
        WARNING: No python installation configured and autoconfiguration
                 failed.  See http://www.boost.org/libs/python/doc/building.html
                 for configuration instructions or pass --without-python to
                 suppress this message and silently skip all Boost.Python 
targets
        warning: Python location is not configured
        warning: the Boost.Python library won't be built
        ...found 1 target...
        => Unwrapping files-to-be-installed.

There is no error, but nothing is built, and the install fails.

>How-To-Repeat:
        Build devel/boost-python. I'm not certain exactly what
        other factors need to be in place to reproduce the problem.
>Fix:
   According to <http://www.boost.org/doc/html/bbv2/reference.html>,
bjam looks in $HOME and $BOOST_BUILD_PATH for user-config.jam. For
some reason setting HOME isn't sufficient in my case. (Possibly being
reset by the shell?) The following patch fixes the problem for me.
