real player 10.4 does not run when installed in FC4test3

[DAVID BENTLEY]

typing realplay at the console gives this output :-

/usr/local/RealPlayer/realplay.bin: error while
loading shared libraries: libstdc++.so.5: cannot open
shared object file: No such file or directory.

When I look for this it does not seem to be installed.

What package that I am presumably missing would
install this file.
