That looks like the fluxus-engine_ss.so not depending on libGLEW.

Have you tried running the commandline racket with LD_PRELOAD? i.e.
something like

$ LD_PRELOAD=/usr/lib/libGLEW.so racket...
(check if you actually have the /usr/lib/libGLEW so file and replace
with different path/version number if necessary)

That command should preload the missing glew library into the racket
process.

Anyway, if the .so does not include the proper dependency that should
be fixed in the build files. The one I have installed here (from a
rather old fluxus version) has got the dependency:

$ ldd /usr/local/lib/fluxus-017/compiled/native/i386-linux/3m/fluxus-engine_ss.so|grep -i GLEW
	libGLEW.so.1.5 => /usr/lib/libGLEW.so.1.5 (0x00e09000)
