i'm probably the wrong one to answert this, but...
i think the naming conventions have chaged from g++2.9x to 3.x. the name 
manglig for C++ methods/functions is diffrent. there might be some option 
to enfore the old behaviour.
python is written is C anyway, so you should not have any problems with it, 
but maybe you're using an interface library like Boost or CXX. that one 
should(must?) be compiled with the same compiler as your extension.

so, yes i do think you thoughts were right, have a look at the libraries 
you link with.
