Installed firewall-config via an "Everything" install.
Then ran firewall-config, which returned this message:
firewall-config: error while loading shared libraries: libstdc++-libc6.1-
2.so.3: cannot open shared object file: No such file or directory.
This might also explain the "unresolved dependencies" message from the
installer regarding the firewall-config package. It had no suggestions
for additional packages to install to resolve the dependency.
Creating a symlink in /usr/lib solves the problem.
ln -s libstdc++2-libc6.1-1-2.9.0.so libstdc++-libc6.1-2.so.3
Wasn't rebuild for Beta2
Fixed in beta 3.
