The simplest way using Fedora is yum install compat-libstdc++ which will install eight or nine versions of libstdc++ for you including 5.0.7. Alternatively, yes, you can build your own from a GCC 3.2 or GCC 3.3 source; if you're going to do that, I'd suggest you base your configure line on the system compiler's (you can see it with "gcc -v").
