Could you please give a try at release 5.5.2-2~exp3 currently in
unstable? A lot of work was done to have libgluegen2 and libjogl2-java
functional on ppc64el (see #779482). Unfortunately I can't test the
resulting scilab build myself because I don"t have access to a baremetal
ppc64el machine. A test on a porter box with VNC makes the X server
segfault but that could be a driver issue.

Thanks in advance,
