It has always worked fine for me on i386 with clang. I suspect that
some libreoffice dependency got compiled with lang/gcc* and therefore
links with /usr/local/lib/gcc*/libstdc++.so.6 while a clang compiled
libreoffice links with /usr/lib/libstdc++.so.6.

If that's the case it might help to create /etc/libmap.conf and add
the following line (adjust the '47'):

libstdc++.so.6	gcc47/libstdc++.so.6
