Attached is a solution using a machin formula 
(http://en.wikipedia.org/wiki/Machin-like_formula) translated into ruby 
from here: 
http://en.literateprograms.org/Category:Pi_with_Machin%27s_formula.

$ time ruby pi.rb 100000 > pi.txt

real  1m44.592s
user  1m44.339s
sys  0m0.212s

No effort has been made to optimize, but it seems to have a reasonable 
running time.
