After reboot (or ldconfig) build will still produce an error with 
missing libstdc++.  Manually adding to $LD_LIBRARY_PATH still fixes it.  
I notice that /usr/lib* /usr/local/lib* are not included in 
/etc/ld.so.conf ... by default?  I thought that red hat based systems 
did not typically include /usr/local/lib in the library search path, but 
it seems strange to me that /usr/lib is not there.

Thanks for the heads up on this one.
