Well, I don't know anything about Ruby, but here's
how I do it for C programs (compiled to .exe that
write to stdout).
import os
factor_program = 'factor! -d200 ' # factor!.exe from MIRACL
n =
'50818429800343305993022114330311033271249313957919046352679206262204589342623811236647989889145173098650749'
# call external program and capture stdout
the_output = os.popen(factor_program+n).readlines()
print 'n: %s' % n
for i in the_output:
print i,
## n:
50818429800343305993022114330311033271249313957919046352679206262204589342623811236647989889145173098650749
