The best thing to do would be to find out who built the library, and
ask him to make a new one with the correct soname.
Barring that, I suppose you could fix the file with emacs "hexl"
mode or with some other binary editor. The strings are
null-terminated. Just find the ".88" and glom a 0 byte on top of
the ".".
But really, it would be much better to ask for the library to be
rebuilt. Otherwise the problem just comes back with the next
version.
