How? Did you try the system-wide Pyrex?
If so, instead try doing
sage -cython filename.pyx
etc.
By the way, when you do
sage: load foo.spyx
a working .so file like you want is actually
created. It is put in
$HOME/.sage/spyx/the_hostname_of_your_computer
So you might just load your file then use that.
Currently it is deleted when you exit, since
there were some subtle problems with
leaving it sitting around so it doesn't have to
be recompiled each time you load it (mainly, I was
worried about having tons of these files wasting disk
space). I will likely turn caching back on though,
so that
sage: load foo.spyx
will only take time the first time around.
Actually, this caching thing is I think just
a matter of changing the default to
use_cache=True in each function
in SAGE_ROOT/devel/sage/sage/misc/cython.py
