We would add a check for autoconf >= 2.64 during the bootstrap sequence. 
But this not solve the issue for SLES11sp3.
I did find people trying to support both 2.63 and >= 2.64 [1] but it has 
some downside. It might be a way to do it.

One way to solve the issue would be to do daily distribution tarballs 
(signed of course) so you dont have to bootstrap everything.

Cheers !
