I'm not sure where I'm going wrong and I'd appreciate some advice.
Embedded Python is more useful when you can load dso's.
I've figured it out, more or less. When I link to libpython2.3.so rather
than the static Python library it works fine. Doesn't answer the
question of why my other program suddenly stopped working re: importing,
but it does fix it.

# The boost-jam embedding example
exe embedding
        : # sources
        embedding.cpp
        : # requirements
        <threading>multi        # my system's Python library is threaded
        <find-library>python2.3
        <find-library>boost_python
        ;

which imports sha without incident. Except it doesn't set the include
path, so the same jamfile won't both compile my code and link it. So now
I just have to work out the arguments to get it to link with the shared
library and set the include path properly... perplexing.

Thanks for any advice,
