Not quite, according to what you report it requires an older
version of a _runtime_ library:

tm> /usr/bin/ld: warning: libstdc++.so.5, needed by 
tm> /usr/local/share/pi-1.3.6-Lite/lib/liblcg_AIDA_AnalysisFactory.so, not 
tm> found (try using -rpath or -rpath-link)

Fedora like other RedHat systems had older versions of the
runtime libraries, for backward compatibility in cases like
this, and in packages whose name begins with 'compat-....'.

Now, I have got a Fedora 4 install somewhere, lets see...

It is one of the two 'compat-libstdc++-...', probably the '33'
one. You can install both ''just in case'' :-).

Uhm I have also tried 'yum provides libstdc++.so.5', but it
seems to work only for installed packages, probably from the
RPM database.

BTW, congratulations on a question that reported sufficient
context and details to be useful... They are quite rare, in
this mailing list or elsewhere.
