It is most likely that a libtool .la file on the system includes 
mention of /usr/lib/libstdc++.la.  That would explain the problem.

It is not usually legal to mix-and-match libstdc++ implementations 
because different versions of GCC don't always produce the exact same 
ABI and because template implementations may differ.  As a result, all 
libraries used by the application should be based on the same version 
of GCC and the same libstdc++.
