Ah, I guess there is no standard conversion for these things into
chicken.

For this particular symbol, You have to compile and link in
"static_initializer.cpp" in src/arx/python.  It sets a static
variable.

If you build the python bindings, there will be both a libarx.a and
libarx.so in build/arx.  You will have to link that in as well.  It
might be possible to hack the SConscript file, but I don't think that
SCons understands chicken :(
