version or path issue w/ libstdc++.so ?

I use PasswordSafe on my Windoze PC, and wanted to install it on my
Fedora PC. So I got the binary from http://www.semanticgap.com/myps/ and
did a make install as instructed.

However, when I try to run it, I get the following error:

$ MyPasswordSafe
MyPasswordSafe: error while loading shared libraries: libstdc++.so.5:
cannot open shared object file: No such file or directory

Running 'locate':
$ locate libstdc++.so
... 
/usr/lib/libstdc++.so.6.0.3
/usr/lib/libstdc++.so.6
...

$ echo $PATH
/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/jamoore/bin

So, it turns out I don't have "ibstdc++.so.5" on my system (FC3), but I
do have "ibstdc++.so.6". I'm guessing this is a later version???

Q: Do I have a version issue, or a path issue?

Thanks,
Jay
