I recently installed Zenwalk 7.2. I have had a few strange little problems, the latest of which poked its head up when I installed the gnome-games package. When I tried to open one of the games, I got nothing, so I went to the terminal to see if there was something wrong. I got this:
mahjongg: error while loading shared libraries: libffi.so.5: cannot open shared object file: No such file or directory
Well, this is silly, I thought to myself. Maybe Netpkg missed a dependency? No, libffi is already installed. Hmm.
I guess it's time to make a symlink!
$ su -
# ln -s /usr/lib/libffi.so /usr/lib/libffi.so.5
...and now I can play Mahjongg. I suppose a recompile could also fix the problem, but I'm a Slacker and prefer the simpler solution.
tl;dr There's a symlink missing in the libffi package that would allow running some software (including the games in the gnome-games package).
