[Rivet] Problems installing rivet

[Andy Buckley]

Hi Alex,

Can you send us a copy of your config.log file? It looks to me like
either the Rivet Python module has not been built at all (possible if
the Python development headers e.g. Python.h are not present on your
machine) or that it has been built but is not present in your PYTHONPATH.

To get a bit more information, can you try running "rivet -v" to get
more verbose information about the failed loading of the "rivet" module
and send us the output. Also, try running "python" to get to the Python
interpreter prompt, and type "import rivet": the output from that would
also be useful... and maybe enough to help *you* find out why the module
isn't being loaded :)

Cheers,
Andy
