If you have a 64-bit Linux, you may have to install additional 32-bit libraries.
On the latest Ubuntu or Debian 64 bit (Wheezy), please do:
aptitude install multiarch-support binutils-multiarch dpkg --add-architecture i386 aptitude update aptitude install libX11-6:i386 libgdk-pixbuf2.0-0:i386 libgtk2.0-0:i386 libsqlite3-0:i386
The last two lines are actually one line.
Ubuntu users may have to add the multiarch sources in /etc/apt/sources.list
On older Ubuntu or Debian 64 bit distributions, do:
sudo apt-get install ia32-libs
In addition, you may need:
sudo apt-get install ia32-libs-gtk
If the program says it cannot find the sqlite3 libraries, you can download them from here (choose the i386 version), and install the downloaded file with these two commands at a root command prompt:
dpkg -X your_downloaded_lib_file_i386.deb /emul/ia32-linux (Enter) ldconfig (Enter)
