My understanding is that conflicting version of libraries are a problem. If I 
include FLTK in my build, I have libstdc++.dylib from both gcc 4.2.1 and gcc 
4.4.2 ... which *might* create troubles, but that does not appear to be my 
problem (or yours).

You are linking against libgcc_s.1.dylib from Apple's gcc 4.0.2 (?) and 
MacPorts gcc 4.3.? ... while I'm linking against Apples gcc 4.2.1 and Finks gcc 
4.4.2. 

I'm not expert in interpreting the back trace, but if I understand correctly ...

        http://www.caf.dk/cafonly/gnu/gdb/gdb_42.html

... the bus error for your occurs in 

        #0  0x03ca4156 in __gnu_cxx::__exchange_and_add ()
        #1  0x03c48526 in std::locale::operator= ()

... and for me, in close proximity to your example 

        #0  0x0282902f in std::locale::operator= ()

I'm not sure what "std::locale::operator= ()" refers to, but I'd guess it is 
either libstdc++.6.dylib or maybe libgcc_s.1.dylib. Any thoughts?
