The current version is libstdc++.so.6.0.8, corresponding to gcc-4.1.1. libstdc++.so.5 corresponds to gcc versions 3.2.x and 3.3.x. The error means you are trying to compile a binary compiled by g++ of that vintage but you are missing the required shared library. There is absolutely no way to just try to fake it by fooling it into using an older version of the library, that is the whole point for having versions to these things -- they are not forward compatible. You don't have to recompile the app, but you need to install a functioning libstdc++.so.5 on your system. Most distros have this as a simple package that you can easily install without having to compile anything. Look for "libstdc++-5" or similar in your package list. Or alternatively, install your distro's gcc-3.3 package. Failing all of that, download and build the source to gcc-3.3 yourself, and then insure that the installed libstdc++.so.5 is either in the system location or in the LD_RUN_PATH when trying to run the binary.
