You're misreading the error message:

libstdc++-libc6.2-2.so.3 is the file that doesn't exist. Its a rather
ancient copy of libstdc++ from Red Hat 6.2, which almost certainly
doesn't exist in a normal Ubuntu installation. It used to be in Fedora
as part of the compat-libstdc++-296-2.96 package, but Fedora dropped it
around FC-4.

So, either, you should convince whomever compiled that library to
recompile it against a modern version of Linux (without any compat-*
libs installed), made in the last 5 years, or you could find an old copy
of the Fedora Core 4 RPM, unpack the libraries from the rpm, put them
in /usr/lib, and hope that is the only ancient library you need.

Hooray for closed source, eh?
