This is just a warning, but if you want to be sure, run
and make sure that libstdc++_shared-2.3.4-stub.so is not found in any of the directories listed.
If it is, re-set the LD_LIBRARY_PATH env. variable, omitting that directory, e.g.
export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:<all other lib dirs except the one containing the libstc library>
