Thanks, still can't reproduce here on Ubuntu, but I found a few messages 
about this warning from Googling around - it appears to be a Red-Hat 
specific extension to GCC that chucks out a warning for every single member 
of a class that has default visibility of hidden :-((   It may even be 
specific to Fedora-7 and your gcc-4.1 for all I can tell as it appears to 
have caused quite a few folks problems.

Can you try again with the option cxxflags=-Wno-visibility added?

Thanks, John.
