[NCLUG] rpm not recognizing library

[bsimpson at att.net]

On my recently installed Fedora Core 4 I am trying to add some
old tools.  One of them, pgp, is in rpm format.  When I run
rpm to install it, I get the following error:

 error: Failed dependencies:
         libstdc++.so.2.8 is needed by pgp-6.5.2-free3-rsaref.i386

I copied over libstdc++.so.2.8 into /usr/lib from a FC3 installation,
but I still get the same error.  My guess is that rpm wants to see it
in its own database.  How do I do this?
