java2 su mozilla

[Ultrakorne]

ho provato ad installare le j2sdk1.3 su mozilla 1.3.1 ... ma avviandolo 
mi da questo errore:
[EMAIL PROTECTED]:~$ /usr/local/mozilla/mozilla
LoadPlugin: failed to initialize shared library 
/usr/local/mozilla/plugins/java2/plugin/i386/ns600/libjavaplugin_oji.so 
[libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file 
or directory]

ho controllato, quei file esistono e sono nella corretta dir...
