<start magic ball mode>
you have multiple libGL on your system, and out-of-luck you are not
picking the right one at startup.

What happen if you run glxgears or glxinfo (which should be installed
by default on your linux station) ?

If they both work, simply set LD_PRELOAD to the correct libGL as a
temporary fix:

$ LD_PRELOAD=/opt/my/exotic/path/libGL.so ./DicomImageViewer


</start magic ball mode>
