All the automatic installation portions fail on linux x86_64 bit versions.
Need a compiled version for platforms such as Fedora Core 6 x86_64
If you change that to: http://autopackage.org/downloads/latest/x86/autopackage.tar.bz2
then you get the 32 bit version, which works fine. The install and the install of the gui work. The application is installed, however the CELstart application uses 32 bit libraries, which are not found.
Running from a command prompt
