I tried that without success, but I managed to get Fluxus to start by 
setting:

   (current-library-collection-paths
    (path-list-string->path-list
     (or (getenv "PLTCOLLECTS") "")
     (or (ormap (lambda (p) (and p (directory-exists? p) (list p)))
                (list (let ([v (getenv "PLTHOME")]) (and v (build-path v 
"collects")))
                      (find-executable-path "fluxus-0.12" "collects")
; "fluxus-0.12" above should be replaced by the name of the program...
; ...as entered on the command line, to avoid having to set $PATH
                      "/usr/local/lib/plt/collects" ; Unix only
;                     "/boot/apps/plt/collects" ; BeOS only
;                    "c:\\plt\\collects" ; Windows only
	))
         null)))

as hinted in:
http://www.cs.rice.edu/CS/PLT/packages/doc/mzscheme/node157.htm

and setting lots of environment variables...

Welcome to fluxus
libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering

This may hurt performance.

So, some element of success.


I'm not worried about the indirect rendering, as this is on my desktop:

01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G550 AGP 
(rev 01)

which isn't exactly a high performance 3D card.
