I've used libturbo-jpeg for a couple years with x2go after I first learned about it.

You might check your Distro...  but at least for Ubuntu I believe libturbo-jpeg is the default installed by Ubuntu now.

     NOTE:   in the following - I did have to install "libjpeg-turbo-progs" separately

On my Ubuntu 13.10 x64 system if I run Synaptic and search for "libturbo" I find:
Independent JPEG Group's JPEG runtime library (dependency package)
 
libjpeg8 dependency package, depending on libjpeg-turbo8.
You might do the same on your Distro to find out what libjpeg is being used today.
