[Buildroot] macro `AM_PROG_LIBTOOL' not found

[Joseph G. Boike]

Hi,
I'm trying to cross compile buildroot for and Atmel at91sam9260 ARM 
processor and keep getting the same error below.
I started w/ a clean buildroot subdirectory and used the default make 
(make at91sam9260_defconfig) setup.
My native autoconf, automake and libtool are all in /usr/bin
The error references m4_pattern_allow.  Where do I add that?  How do I 
keep it if I get a new version of buildroot?
Regards,
Joe
