I tried this today. I had prepared myself for a lot of work, but I was
surprised to find that the build procedure was very simple!

More or less, on Fedora 19:

# this isnt like the instructions above, but the fedora repo guile is
# seemingly pretty okay
yum install guile* 

#the clone took about 10 minutes
git clone git://

#make takes a loong time, much more than a normal emacs
./ && ./configure && make

The build took 53 minutes including the time to clone the first time.
The second time took only a couple of minutes. This was on a fairly
beefy machine.

m-x tetris, and m-x zone worked fine!

(eval-scheme "(define (fact n) (if (= n 0) 1 (* n (fact (1- n)))))")
(eval-scheme "(fact 23)") => 25852016738884976640000

also worked fine!

I find this pretty awesome. I'm, hmm, awestruck!
