Troubleshooting with strace

Hi fellow admins, the other day my X11vnc broke and I have no idea how, possibly while trying to get Street Fighter II: Hyper Fighting working. So no more vnc over ssh, which is no beuno.

When I run /usr/bin/x11vnc it tells me x11vnc: error while loading shared libraries: libvncclient.so.0: cannot open shared object file: No such file or directory

When I try to find libvncclient it's located in /usr/lib/x86_64-linux-gnu/ like it should be (?).

So not sure what is happening. Running 'strace x11vnc' gives me this:

Imgur

It seems like a lot of stuff is not present, or some symbolic links are broken. Is any one able to give me an indication of what the issue might be, or perhaps advise me where to look next in my attempts to get this fixed?

Thanks!
