grub2 not compiling - grub_gettext error

[KESHAV P.R.]

Compiling grub2 for x86_64-UEFI

./configure --with-platform=efi --target=x86_64
--program-transform-name=s,grub,grub2, --enable-efiemu
--enable-mm-debug --enable-grub-fstest --enable-grub-mkfont
--disable-nls --prefix=/grub2_efi_x64

and i386-BIOS

./configure --with-platform=pc --enable-efiemu
--program-transform-name=s,grub,grub2, --enable-grub-emu-usb
--enable-mm-debug --enable-grub-fstest --enable-grub-mkfont
--disable-nls --prefix=/grub2_BIOS

gives the following errors :-

I am not a programmer, but after checking bzr log I guess grub2 bzr
revision 2381 is the culprit.

I also have one more question, can ruby 1.9 and python3 be used to
compile grub2? I read that python3 is incompatible with python2. When
I tried to compile grub2 bzr r2384 with python2 and ruby 1.9, I got
the following errors while using autogen.sh command :

genmk.rb: warning: shadowing outer local variable - util
genmk.rb: warning: shadowing outer local variable - program

lines repeating many times but the configure still continues. With
ruby 1.8 these errors do not occur. I use Archlinux x86_64 (it is a
rolling release distro) and the ruby version currently available is
1.9.1 . Can these errors be ignored or will they affect the compiled
program?

In GRUB2 Manual http://grub.enbug.org/Manual , the grub2 shell help
command is described as "a command that annoyingly scrolls all the
useful commands past your screen size". Any idea of introducing a
pagebreak option like "help -b" that will wait for the user to press
down arrow key or the spacebar or the like to read the entire list of
commands. On the other hand the entire list of commands can be seen by
pressing just <TAB> at grub> prompt, although the list looks awkward.
This "srcolling past screen" behaviour of help command will become a
problem in case of grub rescue shell as tab completion does not exist
in that. So please change it. Thank you.
