Old program that wants libstdc++.so.2.8

Hi,
I downloaded a copy of Acrosslite from Litsoft and am having this problem. Doubleclicking it does nothing. typing ldd acrosslite1.2 gives a list of libraries that it needs and only one is missing: libstdc++.so.2.8. the file date on the executable file is in 1999.

I looked in usr/bin and I see that I have libstdc++.so.5 and also libstdc++.so.5.0.7

Googling for it lists a lot of sites with RPM packages, but i thought RPMs were for RedHat and Debian distributions used apt-get or something like that.

As you can tell, I'm new at this.

So, If I do find a way to get this lib, can I use it without screwing up anything else that depends on the newer one? Can I install it somehow for only this one program?

Or, if it would be simpler, does anyone know of another program that will open and print .PUZ files. (these are crossword puzzle files)

Thank you for any help you can give me,
Don Jungk
