just tried to run new synapse-client on ubuntu 7.10, and was a no go. Here's the output of an ldd command to check if all shared libraries are present. Weirdly enough, as you can see, libstdc++.so.5 is missing:

ubuntu@ubuntu:~$ ldd /home/ubuntu/Desktop/synapse

Answer

The short answer is to sudo apt-get install libstdc++5,

If you need other libraries, you can do this without installing a full X11 desktop

  > apt-get install libx11-6
  > apt-get install libxaw7
  > apt-get install libstdc++5
  > apt-get install libfreetype6
