fail.

If you use a development snapshot or want to hack on GRUB you may
need the following.
-* Python 2.5.2 or later
+* Python 2.6 or later
* Autoconf 2.60 or later
* Automake 1.10.1 or later
-* Autogen 5.10 or later
Prerequisites for make-check:
3. Type `./autogen.sh'.

4. Type `./configure' to configure the package for your system.
If you're using `csh' on an old version of System V, you might
need to type `sh ./configure' instead to prevent `csh' from trying
