gnulib-tool: *** cannot find ./configure.ac

[erobles]

hi!

I  have downloaded   gnulib through git and cvs,  and  i tried to 
import  getaddrinfo module, but  i only got the message mentioned in the 
subject:

$ gnulib-tool  --import  getaddrinfo

gnulib-tool: *** cannot find ./configure.ac
gnulib-tool: *** Stop.

Do you have any sample configure.ac file , this is because i dont have 
idea how can i make it :-P


by the way i have using ubuntu 9.04.


thanks  and i appreciate your time  to read it  at the end!
