No subject

the cause of this failure, just a response to something else which has
already gone wrong:

> 10): Symbol not found: __ZN5Rivet3Log12showLogLevelE

I *think* this indicates that the libRivet.so library doesn't contain a
symbol that it requires (from the log message system), and this is made
visible when Python tries to use the _rivet Python module: _rivet
shouldn't itself have this symbol defined. I don't know exactly what is
going on here... possibly it's as simple as the module search path being
different on a Mac. But I don't really have a Mac to test on, either, so
I'm shooting in the dark.

Can any of the other Rivet developers or users reproduce this problem
(ideally during a rivet-bootstrap --install-boot run on a Mac OS X 10.6
system)?
