I found somemore information about my libstdc++ problem.  Here is the 
results from ls -l /usr/lib/libstdc++*

2022860 Aug  1 10:05 libstdc++-2-libc6.1-1-2.9.0.a

Are all of those links setup correctly to work with the most recent 
libstdc++ snapshot?  The only unusal thing I notice was that my older 
versions of libstdc++(which I moved to another directory to prevent any 
conflicts) had files like libstdc++-3-libc.2-2-2.10.0 but the most recent 
install of libstdc++ didn't create a file like that.  I wonder if that is 
what is causing some of my problems?
