[ILUG] libstdc++.so.5 not available / Error installing Firefox 1.0.4 on Mandrake 10.2.

[Seán Mac Suibhne]

While trying to install Firefox1.0.4  on Mandrake 10.2 I get the following 
error:

[root at localhost firefox-installer]# ./firefox-installer
./firefox-installer-bin: error while loading shared libraries:libstdc++.so.5: 
cannot open shared object file: No such file or directory

libstdc++.so.5 is not available but libstdc++.so.6 is in /usr/lib. 

I was wondering if there was something I can do to get the installer to use 
libstdc++.so.6?
