firefox error libstdc++.so.6: cannot open

["C.T.F. Jansen" <frank.jansen@actrix.gen.nz>]

Greetings,

installed firefox but when it is run it falls over with error message :

firefox: error while loading shared libraries: libstdc++.so.6: cannot 
open shared object file: No such file or directory

This file is at   /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.13

Tried putting a symlink in /lib  /usr/local/lib and the main firefox 
directory which has the  firefox files,  /opt/firefoxx/firefox . The 
symlink is

libstdc++.so.6 -> /usr/lib/libstdc++.so.6.0.13

None of the symlinks have worked yet, same error message. It is an amd64 
system.

Any ideas on how to cause firefox 17.0 on debian squeeze to pickup the 
"missing"
library ?

Thanks.
