This is not a bug in Gentoo Linux this is because the plugins you mentioned are only available to us as binaries so we cannot recompile them to work with the new gcc-3.1 symbol mangling system. As soon as the vendors release gcc-3.1 compatible versions we will incorporate them for our users web-surfing pleasure.
Created attachment 1606 [details] My quick hack Extract the following into /usr/lib/mozilla and it will create libc++mem.so and run-mozilla.sh (replacing your old one) and you're all set as far as Flash. As far as Java there is no fix available because of the new C++ ABI used by gcc3.1 and no Java vendor has a JRE compiled with gcc3.1.
