What works for me (with Mandriva) is to su to root and create a symbolic
link from /usr/lib/libstdc++.so.6 (or whatever version of the C++ runtime
is used in FC 4) to /usr/lib/libstdc++.so.5.

(First take out the old .so.5 library and uninstall the pieces of Firebird
that you have already installed, of course. Uninstall instructions are in
the release notes.)

Then, add the symlink before you try to reinstall the rpm:

ln -s /usr/lib/libstdc++.so.6 /usr/lib/libstdc++.so.5

If that doesn't work properly, repost your question on the firebird-devel
list. The person who does the Linux builds doesn't watch this list.

Also, for Superserver on FC4 you you will need to use the NPTL build.
