You may have multiple versions of libstdc++ in multiple locations. Try typing
Code:
locate libstdc++-libc6.2-2.so.3
If you come up with something (for example "/usr/lib/someotherstuff/libstdc++-libc6.2-2.so.3") then make sure that the direcory exists within
/etc/ld.so.conf. If not, then add it and run
ldconfig as root.
Hope that helps...
