I think it's complaining because it's trying to link against a static 
libstdc++, i.e it's libstdc++.a that's not compiled with -fPIC.
The solution, change the

I've not looked at this for months, but at one time there was this 
added  to the SConstruct file :-

# EVIL HACK - force static-linking for libstdc++ - create a symbolic 
link to the static libstdc++ in the root

Basically you want to remove that if it's still there.

Something like this is what I did in a very old patch :-
