There are two main versions of the C++ ABI in the free world. That's one of the fun things we have to deal with. We solve it by supplying a wrapper around g++ that compiles everything twice; once with a compiler that supports one ABI and once with a compiler that supports the other one.
Some fun filename mangling and parameter massaging takes place behind the scenes in order to make that work.
It now works well enough that I've managed to build a proper autopackage for Scribus 1.3.2 and install it locally (non-root) on charybdis, my desktop machine.
This is good<tm>.
