Hi,
It probably means matcont tries to load the libstdc++ library, but cant find it. Check if it is installed. Normally it should be installed in the /usr/lib directory.
If it is installed make sure that ldconfig has it in it list.
Code:
$ ldconfig -p | grep stdc
libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
libstdc++.so.5 (libc6) => /usr/lib/libstdc++.so.5
Otherwise you probably have to install it.
