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.
