gnumeric for Mac?

[David Romano <romanod math grinnell edu>]

My guess is the answer is no, but I thought I'd ask anyway: is 
there any way to get gnumeric for Mac OS X?

If not, I have another question: I have .gnumeric files, but only
have terminal access to a linux machine.  Is there some way I could
convert these to tab-separated ASCII files? (Or .csv files, if that's
not possible.)

Any help would be greatly appreciated.

Thanks!
