Hummm, try to *really* understand what's going wrong and where. For 
instance, in the install (lib) dir, if I do "nm --demangle libstdc++.so 
| more | grep '~basic_iostream'" I get:

And you?

Then, do the same for io-inst.o in the build (src) dir. Should be the 
very same set. This should tell us something...
