[Fluxus] error "Unable to create direct context rendering for window"

[Peter Ngo]

Hello again everyone,
i reinstalled ubuntu 8.10 and tried to build the last git version.
It compiles fine but i get this:

==========
Welcome to fluxus.
Type (help) for info.
freeglut (fluxus-0.16): Unable to create direct context rendering for
window 'fluxus scratchpad 0.16'
This may hurt performance.
SIGSEGV fault on (nil)
pid # 28167 run gdb "gdb ./mzscheme3m 28167" or kill process.
==========

any ideas?
