[Fluxus] 64bit ubuntu

[ub]

hey there,

i'm having a problem running fluxus on 64bit ubuntu 10.10. it does start 
up, but when i run (self-test) fluxus segfaults at the (every-frame) 
test. i did some basic tests on the repl though, and it seems, that not 
the threading is the problem, but any kind of gl-operation in the loop.
i have an nvidia card and use the nvidia drivers. i was thinking, that 
maybe that's the problem, first because of the gl connection and then 
because i had a similar problem on my old laptop with flaky drivers.
compiling went fine after sorting out the dependencies and fixing a typo 
in one include file.
when i try to run fluxus in gdb it breaks here:

(gdb) run
Starting program: /usr/local/bin/fluxus
[Thread debugging using libthread_db enabled]
[New Thread 0x7fffef87b700 (LWP 2993)]

Program received signal SIGSEGV, Segmentation fault.
scheme_gmp_tls_unload (s=0x7fffeeeba418, data=0x0)
     at ../../../racket/src/gmp/gmp.c:5813
5813      s[0] = 0;

is it racket maybe?

any help welcome!

thanks+ciao,
ub
